    x86emul: fix test harness build for gas 2.36
    
    All of the sudden, besides .text and .rodata and alike, an always
    present .note.gnu.property section has appeared. This section, when
    converting to binary format output, gets placed according to its
    linked address, causing the resulting blobs to be about 128Mb in size.
    The resulting headers with a C representation of the binary blobs then
    are, of course all a multiple of that size (and take accordingly long
    to create). I didn't bother waiting to see what size the final
    test_x86_emulator binary then would have had.
    
    See also https://sourceware.org/bugzilla/show_bug.cgi?id=27753.
    
    Rather than figuring out whether gas supports -mx86-used-note=, simply
    remove the section while creating *.bin.
