[PATCH] osflags: use pkg-config for systemd support Recent versions of systemd don't ship with libsystemd-daemon.so anymore, but instead use libsystemd.so for everything. This is obviously problematic for using the same LDFLAGS on old systemd and new systemd. So, they also ship compatability pkgconfig files, which use the old names but return the new library. So, the most portable way to support both old and new systemd is to use pkgconfig. It's not a problem either, since systems that use systemd are bound to also have pkgconfig installed.
Fix cross compilation src/osflags hard codes the build architecture pkg-config. After making it substitutable and substituting it from the build environment, iodine cross builds successfully.
