#51642: gcc49 @4.9.3: does not honor -march=native

Comment (by noloader@…):
This is probably related to `-Wa,-q`. When I originally tried to use it, I
used it with a typo: `-Wa,q`. The typo resulted in:
{{{
$ /opt/local/bin/g++-mp-4.9 -Wa,q -c test.cxx
as:file(q) Can't open source file for input! No such file or directory.
}}}
At that point, I thought the compiler did not support the option.
Now that the typo has been corrected, it appears the option is supported:
{{{
$ /opt/local/bin/g++-mp-4.9 -Wa,-q -c test.cxx
/opt/local/bin/as: assembler (/opt/local/bin/clang) not installed
}}}
