powerpc/xmon: Reapply "Relax frame size for clang"

This is a manual revert of commit 7f3c5d099b6f ("Revert "powerpc/xmon:
Relax frame size for clang"") but using ccflags-$(CONFIG_CC_IS_CLANG)
which is shorter.

Turns out that this is reproducible still under specific compiler
versions (mea culpa: I did not test every supported version of clang),
and even a few randconfigs bots found.

We'll have to revisit this again in the future, for now back this out.
