Bug#967075: haskell-ghc-lib-parser: FTBFS on mips* and s390x: /usr/lib/ghc/include/stg/SMP.h:390:2: error: #error memory barriers unimplemented on this architecture

[John David Anglin]

Same error occurs on hppa.

The "sync" instruction is simplest barrier on hppa, so the powerpc asm would 
work:

#elif defined(powerpc_HOST_ARCH) || defined(powerpc64_HOST_ARCH) \
    || defined(powerpc64le_HOST_ARCH)
    __asm__ __volatile__ ("sync" : : : "memory");
