Compile log

When running configure for udev and the x86 ABI, it tries to search for libpcap which it can't find. libpcap also isn't multilib-enabled.

It's not libpcap, but libcap, and libcap is multilib enabled:

$ grep cap_init systemd-210/configure.ac
AC_SEARCH_LIBS([cap_init], [cap], [], [AC_MSG_ERROR([*** POSIX caps library not found])])

$ nm -D --defined-only /usr/lib32/libcap.so.2.22 |grep cap_init
00001240 T cap_init

$ qlist libcap |grep libcap.so.2
/usr/lib32/libcap.so.2.22
/lib64/libcap.so.2.22
/lib64/libcap.so.2
/usr/lib32/libcap.so.2

$ emerge -pv libcap

+  01 Mar 2014; Samuli Suominen <ssuominen@gentoo.org> udev-210.ebuild,
+  udev-9999.ebuild:
+  Restore ac_cv_search_cap_init= as an econf argument since we only need the
+  libcap at build time for the sys/capability.h, not cap_init() from -lcap wrt
+  #503100 by "Philipp"

Sorry about that. I didn't notice this because I had sys-libs/libcap built with ABI_X86="32"

Thanks for reporting!
