Subject: [RESEND-3 PATCH trivial] Avoid conflict with host definitions when cross-compiling
Date: Wed, 15 Jul 2015 11:41:42 +0300	[thread overview]
Message-ID: <00e101d0beda$13637ee0$3a2a7ca0$@samsung.com> (raw)

 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).

Signed-off-by: Pavel Fedin <p.fedin@samsung.com>

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
