powerpc: Fix error when cross building TAGS & cscope
Currently if I cross build TAGS or cscope from x86 I get this:
% make ARCH=powerpc TAGS
gcc-4.8.real: error: unrecognized command line option ‘-mbig-endian’
GEN TAGS
%
I'm not setting CROSS_COMPILE= as logically I shouldn't need to and I
haven't needed to in the past when building TAGS or cscope. Also, the
above completess correct as the error is not fatal to the build.
This was caused by:

powerpc: Add ability to build little endian kernels
The below fixes this by testing for the -mbig-endian option before
adding it.
I've not done the same thing in the little endian case as if
-mlittle-endian doesn't exist, we probably want to fail quickly as you
probably have an old big endian compiler.
