[OE-core] [PATCH] uninative: Add allow-shlib-undefined to BUILD_LDFLAGS and drop other workarounds

[Burton, Ross]

The dbus-glib-native one hits a few times but the only other place it
has broken so far is in cmake-native:

bin/cmake: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not
found (required by
TOPDIR/tmp/work/x86_64-linux/cmake-native/3.10.3-r0/recipe-sysroot-native/usr/lib/libexpat.so.1)

Is expat using rpaths or something and picking the wrong libc?
