 Well, FWIW my port of gcc 2.95.4 supports -march= (by aliasing it to
-mcpu=, but the option is passed down to gas as is) to cooperate with
current binutils, but its support for -mabi= varies depending on the
configuration: mips64el-linux-gcc does support the option, but
mipsel-linux-gcc does not.  I suppose others may also want to have -march=
support in 2.95.4 for binutils compatibility, especially as AFAICS 2.95.4
has a huge speed advantage over later versions of gcc.
