   When assembling grub-core/kern/i386/pc/startup.S, gas on some platforms
chokes on this line:

        movl    $((LOCAL(bypass_table_end) - LOCAL(bypass_table)) / 2), %ecx

  Because on non i386-linux targets, '/' is used as a comment delimiter
for compatibility purposes.  This can be overridden with the --divide
switch.

   Since the default for gas on these platforms is to use he division
operator as a comment delimiter, the "-Wa,--divide" flags need to be
passed on the gcc command line when assembling such files.

Can we just use>>  1 instead?


  Sure, that works for me :).
