Commit 0f71dcfb4aef ("powerpc/ftrace: Add support for
-fpatchable-function-entry") added a script to check for
-fpatchable-function-entry compiler support. The script expects compiler
to emit the section __patchable_function_entries and few nops after a
function entry.
If the compiler understands and emits the above,
CONFIG_ARCH_USING_PATCHABLE_FUNCTION_ENTRY is set.
So teach dummy-tools' gcc about this.
