Drop this comment. Neon may be missing from other ISA levels too (i.e.
this fix is not specific to armv5).

Shouldn't this be checking for neon in TUNE_FEATURES rather than
TUNE_CCARGS_MFPU? It should also probably be conditional on the _arm
over-ride since neon will be missing from
TUNE_CCARGS_MFPU/TUNE_FEATURES for other architectures. Since big
endian ARM doesn't use the _arm over-ride you will also need a
duplicate line with the same logic with the _armeb override too. See
the lines below which do the equivalent for _powerpc / _powerpc64 as a
reference.
