--- Comment #21 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
FWIW in the environment:

COLLECT_GCC_OPTIONS = '-B' '.' '-v' '-flto' '-MMD' '-MF' 'aaaa'
'-mcpu=cortex-a72' '-mfloat-abi=hard' '-mtls-dialect=gnu' '-marm'
'-march=armv8-a+crc+simd'

So is this correct, or should an extra argument have been inserted after the
-MMD option at this point?
