[PULL for-6.2 2/2] tests/tcg/ppc64le: Fix compile flags for byte_reverse

["Cédric Le Goater" <clg@kaod.org>]

From: Richard Henderson <richard.henderson@linaro.org>

With a host compiler new enough to recognize power10 insns,
CROSS_CC_HAS_POWER10 is true, but we do not supply the -cpu
option to the compiler, resulting in

/tmp/ccAVdYJd.s: Assembler messages:
/tmp/ccAVdYJd.s:49: Error: unrecognized opcode: `brh'
/tmp/ccAVdYJd.s:78: Error: unrecognized opcode: `brw'
/tmp/ccAVdYJd.s:107: Error: unrecognized opcode: `brd'
make[2]: *** [byte_reverse] Error 1
