Support for -fpatchable-function-entry on ppc64le was added in Clang
with [1]. However, when no prefix NOPs are specified - as is the case
with CONFIG_PPC_FTRACE_OUT_OF_LINE - the first NOP is emitted at LEP,
but Clang records the Global Entry Point (GEP) unlike GCC which does
record the Local Entry Point (LEP). Issue [2] has been raised to align
Clang's behavior with GCC. As a temporary workaround to ensure ftrace

Any reason to put in a "temporary" workaround rather than waiting for
this to be fixed?

Pushing for this temporary workaround as the fix ETA for clang is not
available at the moment and the temporary workaround is likely
harmless even on a clang version with the fix included..
