Ross Burton a044db9527 multilib: let pkg-config find architecture-independent .pc files
If a multilib package depends on an allarch recipe that installs an
architecture-independent .pc file it will not be able to find the .pc file as
the recipe gets installed into the MACHINE sysroot but pkg-config looks in the
MLPREFIX-prefixed sysroot.

Solve this by extending PKG_CONFIG_PATH in multilib environments to include the
architecture-independent path in the MACHINE sysroot
(sysroots/MACHINE/usr/share/pkgconfig/).

# When multilib is enabled, allarch recipes will be installed into the MACHINE
# sysroot, not MLPREFIXMACHINE. This means that anything using pkg-config to
# find an allarch pkgconfig file will fail as the PKG_CONFIG_PATH only looks
# inside the multilib sysroot. Fix this by explicitly adding the MACHINE's
# architecture-independent pkgconfig location to PKG_CONFIG_PATH.
