[PATCH] Alpha CFLAGS fix

Hi Richard.

I noticed you have set -Werror in all alpha architecture
specific makefiles - good initiative. I wish we could do that in general.

But the correct way to alter CFLAGS in kbuild makefiles is to use
EXTRA_CFLAGS.
The following patch fixes this.
You could argue that this is a stylistic issue, but in this way
you follow Documentation/kbuild/makefiles.txt

I stumbled over:
EXTRA_AFLAGS := $(CFLAGS)
I could not realise the purpose with this assignment, and I noticed
that it did not include -Werror, becuse you did hat assignment in
the following line.
Wanted to inform you about it but I see no problem. It is just that
I did not understand it.

In math-emu I see this:
EXTRA_CFLAGS := -Iinclude/math-emu -w
Grepping the src I see no reason to have the -Iinclude/math-emu
Relevant files are prefixed with math-emu (soft-fp, single, double)
I did not fix it, because I cannot compile alpha.
