#     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.
