mesa: Use -Bsymbolic in the linker to locally resolve Mesa-internal symbols.
Normally, LD_PRELOAD will take precedence over your own symbols, which you
want for things like malloc() in libc. But we don't have any local
symbols we would want overridden (like hash_table_insert(), for example!),
so tell the linker to resolve them internally. This also avoids calls
through the PLT.
Saves almost 100k on libdricore's size, and gets us a bunch of the
performance back that we had with non-dricore.
