    tools/gdbsx: fix build with clang 3.8
    Currently building gdbsx with clang 3.8 gives the following errors:
    xg_main.c:783:17: error: 'aligned' attribute ignored when parsing type 
        iop->uva = (uint64_aligned_t)((unsigned long)tobuf);
 note: expanded from macro 'uint64_aligned_t'
    xg_main.c:816:17: error: 'aligned' attribute ignored when parsing type 
        iop->uva = (uint64_aligned_t)((unsigned long)frombuf);
 note: expanded from macro 'uint64_aligned_t'
    According to https://bugs.llvm.org/show_bug.cgi?id=11071, this issue has
    been fixed in clang. But we're not going to get that in 3.8.
    Explicitly disable that warning to fix the build.
