[U-Boot] [PATCH] config.mk: use different host compiler for OS X 10.6

[Andreas Bießmann]

Compiling tools subdirectory on Mac OS X 10.6 (Snow Leopard) complains about
wrong syntax in system includes.

In file included from /usr/include/stdio.h:444,
                 from /Users/andreas/Documents/source/u-boot/include/compiler.h:26,
                 from /Users/andreas/Documents/source/u-boot/lib/crc32.c:15:
/usr/include/secure/_stdio.h:46: error: syntax error in macro parameter list

This can be fixed by reverting the workaround for prior OS X releases in
config.mk conditionally for OS X 10.6 (and maybe above, but this is not covered
by this patch).
