futility is built for the host. However, when cross-compiling,
the target's pkg-config is called to get the library paths which
can add paths from the cross-compilation tree instead of host.
e.g. /build/elm/usr/bin/pkg-config gets called instead of /usr/bin/pkg-config
. /build/elm/usr/bin/pkg-config adds the paths specific to the
cross-compilation target e.g. /build/elm/usr/lib instead of /usr/lib.
This causes linker to complain that files in library paths do not
match the architecture. BFD produces a warning while LLD errors out.
Fix this by passing PKG_CONFIG from host when building futility.
