mips: Remove compiler check in unroll macro

CONFIG_CC_IS_GCC is undefined when Clang is used, which breaks the build (see our Travis link below). Clang 8 was chosen as a minimum version for this check because there were some improvements around __builtin_constant_p in that release. In reality, MIPS was not even buildable until clang 9 so that check was not technically necessary. Just remove all compiler checks and just assume that we have a working compiler. Fixes: d4e6045 ("Restore gcc check in mips asm/unroll.h") Link: https://travis-ci.com/github/ClangBuiltLinux/continuous-integration/jobs/359642821 Signed-off-by: Nathan Chancellor <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
