Note that swrastg can be built with or without llvm: in the first case it is
commonly called llvmpipe [1], in the second case it is called softpipe. They
should both be better than classic swrast.
So you can compile with llvm only on that supported and tested platforms, but
always install the resulting swrastg (rather than classic swrast).
Also note that on current git (will be in 7.12/8.0) swrastg was renamed to
swrast (so there are two swrast now: the gallium one and the classic one, built
under different directories):

[1] example string when compiling with llvm:
GL_RENDERER = Gallium 0.4 on llvmpipe (LLVM 0x208)
