    Fix file-not-found error with clang in gdb.arch/i386-{avx,sse}.c
    
    Clang fails to compile two testcases with the following error:
      fatal error: 'nat/x86-cpuid.h' file not found
    
    This prevents the following testcases from executing:
      gdb.arch/i386-avx.exp
      gdb.arch/i386-sse.exp
    
    Both testcases set additional_flags when building with GCC.
    This commit causes the additional_flags to also be used when
    building with clang.  Note that, while fixing the build, this
    commit reveals several new failures when using clang to build
    the testsuite.
    
    gdb/testsuite/ChangeLog:
    
            * gdb.arch/i386-avx.exp (additional_flags): Also set when
            building with clang.
            * gdb.arch/i386-sse.exp (additional_flags): Likewise.
