mesa: remove patch disabling asm

This was originally added for musl only [1]. Upstream has removed this
option but we reverted that change during an upgrade to fix certain
musl specific compile time issues [2].

I compile tested without this patch on musl-x86 and musl-x86-64 and
don't see the warnings anymore. Similar textrel issues were fixed
upstream so perhaps those helped [3].
