kbuild: remove GCC_VERSION

Browse source 
This was causing some ordering problems.  Remove the up-front evaluation
and just revaluate the compiler version each time we need it.

(The up-front evaluation was problematic because some architectures modify
the value of $(CC)).

@ -1033,9 +1033,9 @@ When kbuild executes the following steps are followed (roughly):
Example:
#arch/i386/Makefile
GCC_VERSION := $(call cc-version)
cflags-y += $(shell \
if [ $(GCC_VERSION) -ge 0300 ] ; then echo "-mregparm=3"; fi ;)
if [ $(call cc-version) -ge 0300 ] ; then \
echo "-mregparm=3"; fi ;)
In the above example -mregparm=3 is only used for gcc version greater
than or equal to gcc 3.0.
