[Buildroot] [PATCH 01/20] Fix util-linux build on MIPS

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

As reported in bug #635, util-linux doesn't build due to missing
constant definitions related to the a.out binary format. We fix this
by hardcoding these constant definitions, as done in newer versions of
util-linux.

Obviously, the long term fix is to upgrade to util-linux-ng, but this
is probably not acceptable for 2010.08.

+Hardcode a.out related constants
+
+The OMAGIC, NMAGIC and ZMAGIC constants, related to the legacy a.out
+binary format, are no longer available in the headers of all
+architectures, due to this binary format being deprecated. For that
+reason, util-linux fails to build.
+
+We therefore take the approach used in newer versions of
+util-linux-ng: hardcoding those values. See
+http://git.kernel.org/?p=utils/util-linux-ng/util-linux-ng.git;a=commitdiff;h=e9eb4dad0ece03914f67f6d1ded74cfbbe694ba4
