On hardened/linux/amd64/no-multilib (and probably other amd64 no-multilib profiles) glibc-2.11.3 gives "Building multilib glibc for ABIs: x86 amd64". The x86 part of this is not desirable and does not work ("configure: error: C preprocessor "/lib/cpp" fails sanity check"). It looks like the ebuild goes down the wrong path in setup_env in files/eblits/common.eblit, where it calls "multilib_env ${CTARGET_OPT:_${CTARGET}}", which for an x86_64 CTARGET has MULTILIB_ABIS="amd64 x86" hardcoded (overwriting the value of "amd64" from the profile). Later calls to has_multilib_profile and get_install_abis include x86 because of this. Reproducible: Always Steps to Reproduce: 1. be on a no-multilib amd64 profile 2. emerge -1 sys-libs/glibc Actual Results: >>> Compiling source in /var/tmp/portage/sys-libs/glibc-2.11.3/work/glibc-2.11.3 ... * Building multilib glibc for ABIs: x86 amd64 * ABI: x86 * CBUILD: x86_64-pc-linux-gnu * CHOST: x86_64-pc-linux-gnu * CTARGET: x86_64-pc-linux-gnu * CBUILD_OPT: i686-pc-linux-gnu * CTARGET_OPT: i686-pc-linux-gnu * CC: * CFLAGS: -m32 -march=i686 -O2 -fno-strict-aliasing -fno-stack-protector * Manual CC: x86_64-pc-linux-gnu-gcc * Configuring GLIBC for nptl <snip> configure: error: in `/var/tmp/portage/sys-libs/glibc-2.11.3/work/build-x86-x86_64-pc-linux-gnu-nptl': configure: error: C preprocessor "/lib/cpp" fails sanity check Expected Results: (successfully) build for just amd64 Portage 2.1.9.42 (hardened/linux/amd64/no-multilib, gcc-4.5.2, glibc-2.11.2-r3, 2.6.36-hardened-r6-m2 x86_64) ================================================================= System uname: Linux-2.6.36-hardened-r6-m2-x86_64-Intel-R-_Atom-TM-_CPU_D525_@_1.80GHz-with-gentoo-1.12.14 Timestamp of tree: Unknown app-shells/bash: 4.1_p9 dev-lang/python: 2.6.6-r2 sys-apps/baselayout: 1.12.14-r1 sys-apps/sandbox: 2.4 sys-devel/autoconf: 2.65-r1 sys-devel/automake: 1.11.1 sys-devel/binutils: 2.20.1-r1 sys-devel/gcc: 4.5.2 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.10 sys-devel/make: 3.81-r2 virtual/os-headers: 2.6.36.1 (sys-kernel/linux-headers) ACCEPT_KEYWORDS="amd64" ACCEPT_LICENSE="* -@EULA" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -march=atom -ggdb -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/gconf /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2 -march=atom -ggdb -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="assume-digests binpkg-logs collision-protect distlocks fixlafiles fixpackages news parallel-fetch protect-owned sandbox sfperms splitdebug strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox" FFLAGS="" GENTOO_MIRRORS="http://gentoo.tiscali.nl/" LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="en en_GB en_US" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://gentoo.tiscali.nl/gentoo-portage" USE="acl amd64 bzip2 caps cli crypt cups cxx dri gmp hardened iconv idn ipv6 justify lzma mmx modules mudflap ncurses nptl nptlonly pam pppd readline session sse sse2 ssl ssse3 sysfs unicode urandom xorg zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en en_GB en_US" PHP_TARGETS="php5-3" RUBY_TARGETS="ruby18" USERLAND="GNU" VIDEO_CARDS="fbdev glint intel mach64 mga neomagic nouveau nv r128 radeon savage sis tdfx trident vesa via vmware dummy v4l" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY
