PATCH 1/1 Avoid conflict with host definitions when cross-compiling

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
