uninative: Add compatiblity version check
If glibc is newer on the host than in uninative, the failure mode is pretty nasty for clusters where the sstate is shared, including the Yocto Project autobuilder. This check aborts the use of uninative in such scenarios where a newer glibc version appears and avoids corruption of sstate caches. We use ldd to check the glibc version since that is included in libc-bin (or equivalent) which locales use so it should always be present. Signed-off-by: Richard Purdie <>
