#     powerpc/64s: Disable pcrel code model on Clang
#     
#     Clang has a bug that casues the pcrel code model not to be used when any of
#     -msoft-float, -mno-altivec, or -mno-vsx are set. Leaving these off causes
#     FP/vector instructions to be generated, causing crashes. So disable pcrel
#     for clang for now.
#     
#     Fixes: 7e3a68be42e10 ("powerpc/64: vmlinux support building with PCREL addresing")
