[PATCH] [PPC64] override command line AS/LD/CC variables when adding -m64 and co for biarch compilers.

[Sven Luther]

Hello,

The following kind of calls currently fails :

  make ARCH=ppc64 CC="gcc-3.4"

Since the code for detecting a biarch compiler and adding the needed 64bit
magic argument fails if the AS/LD/CC commands are overriden in the command
line.

The attached patch fixes this by using the make override and += directive, but
i am not 100% sure this will work without gmake, as i am no Makefile expert.

Friendly,

Sven Luther
