ARCH_USING_PATCHABLE_FUNCTION_ENTRY depends on toolchain support for -fpatchable-function-entry option. The current script that checks for this support only handles GCC. Rename the script and extend it to detect support for -fpatchable-function-entry with Clang as well, allowing clean cross-compilation with Clang toolchains.
