powerpc/trace: Account for -fpatchable-function-entry support by toolchain
So far, we have relied on the fact that gcc supports both
-mprofile-kernel, as well as -fpatchable-function-entry, and clang
supports neither. Our Makefile only checks for CONFIG_MPROFILE_KERNEL to
decide which files to build. Clang has a feature request out [*] to
implement -fpatchable-function-entry, and is unlikely to support
-mprofile-kernel.
Update our Makefile checks so that we pick up the correct files to build
once clang picks up support for -fpatchable-function-entry.
