This patch should no longer be needed. In the 4.0 release, mkoctfile will pass any options that start with "-" through to both the compiler and linker.

This patch makes mkoctfile treat -f* and -m* options passed to it in the same way as -W* ones, i.e. it passes it further along to the compiler. This is handy mostly for e.g. -ffast-math, which can give a noticable speedup in some circumstances. The "-P:" option to mkoctfile serves to pass along arbitrary options.

A second patch updates the usage help for mkoctfile.

Btw, I'm confused at this one:

-W... Pass flags to the compiler such as -Wa,OPTION.

It sounds as though you could pass anything, but I couldn't get -ffast-math through no matter how contrived I wrote it, hence this patch.
