graphics/mesa-dri: fix build with lld 17

Some symbols in mesa's linker version scripts are not always defined,
depending on configuration options. Suppress errors with lld >= 17 due
to these undefined symbols.

This applies to multiple mesa ports, such as mesa-dri, mesa-libs,
mesa-gallium-*, etc. So add the LDFLAGS setting to Makefile.common.
