This builds on amd64 but breaks building xenocara Mesa 17.3.9 with llvm
ie:
common/ac_nir_to_llvm.c:6415:2: error: implicit declaration of function
'LLVMAddPromoteMemoryToRegisterPass' is invalid in C99
[-Werror,-Wimplicit-function-declaration]
LLVMAddPromoteMemoryToRegisterPass(passmgr);
^
Mesa 18.3.2 builds with this llvm 7.0.1 update but updating Mesa
before i386 has switched to lld by default would break the xenocara
build as it requires build-id support in ld for the i965 driver which
ld.bfd doesn't have.
Building Mesa against libLLVM is required to use the radeonsi driver.
