Plenty of people (bug 125905 etc.) are trying to build glibc 2.4 with CHOST=i386-pc-linux-gnu USE="nptl nptlonly" and getting confused by the die message. It would save time overall to adjust the die message when CHOST=i386-pc-linux-gnu: if want_linuxthreads ; then ewarn "glibc-2.4 is nptl-only!" if ! use nptl || ! use nptlonly; then die "please add USE='nptl nptlonly' to make.conf" else ewarn "Your system is not compatible with nptl, probably because of CHOST or /etc/make.profile symlink" die "please add '>=sys-libs/glibc-2.4' to your local package.mask" fi fi
added a message for i386-* CHOSTs: * NPTL requires a CHOST of i486 or better
