#     Restore gcc check in mips asm/unroll.h
#     
#     While raising the gcc version requirement to 4.9, the compile-time check
#     in the unroll macro was accidentally changed from being used on gcc and
#     clang to being used on clang only.
#     
#     Restore the gcc check, changing it from "gcc >= 4.7" to "all gcc".
#     
#     [ We should probably remove this all entirely: if we remove the check
#       for CLANG, then the check for GCC can go away. Older versions of clang
#       are not really appropriate or supported for kernel builds - Linus ]
