Subject: [PATCH 1/1] systemd-multilib: properly install pkgconfig files from
 systemd

previous instructions only copied out libsystemd.so* and libudev.so*
for the m32/mx32 builds, as those are the only libs needed.
however, some packages complain if the .pc pkgconfig files do not
get installed properly, and ultimately try to link against the
x86_64 build, as that is the only .pc files found. remedy that by
copying out all files in DESTDIR/usr/lib{x}32/pkgconfig to
/usr/lib{x}32/pkgconfig
