[Mesa-dev] Build failure of Gallium OSMesa without LLVM

[Matt Turner]

Reported against 17.0.0-rc2 [1], but occurs on master as well

Reproduce with

./configure --with-dri-drivers= --with-gallium-drivers=swrast
--disable-gallium-llvm --enable-gallium-osmesa

Fails linking Gallium OSMesa with undefined references to draw_llvm_destroy.

../../../../src/gallium/auxiliary/.libs/libgallium.a(draw_context.o):
In function `draw_destroy':
/home/mattst88/projects/mesa/src/gallium/auxiliary/draw/draw_context.c:226:
undefined reference to `draw_llvm_destroy'
