  To: linux-kbuild; +Cc: 'Jiri Kosina', trivial

 Certain platforms (e. g. BSD-based ones) define some ELF constants according to host.
This patch fixes problems with cross-building Linux kernel on these platforms (e. g. building ARM
32-bit version on x86-64 host).

If you are not fond of mentioning Cygwin in the comment, feel free to change it to "BSD-based" or
whatever else you feel appropriate
