-----------
gdb: prevent compiler failure: do not compile if cctools-headers is installed.

This prevents the following compile failure which is caused by
bfd/mach-o.h including mach-o/loader.h, which is found in
${prefix}/include instead of gdb's source directory.  The file in
${prefix}/include doesn't define the symbols that gdb needs.
