This patch enables `-fomit-frame-pointer` option by default for PowerPC if -O1
or above optimization level is specified.
GCC already enables this option by default for -O1 or above in all of ppc32,
ppc64 and ppc64le.
This option gives some performance improvements in many programs by reducing
the overhead in method prologue and epilogue.
