`man gcc` always seemed fine to me

in fact, lets read the -ffast-math section:
       -ffast-math
           This option should never be turned on by any -O option since it can
           result in incorrect output for programs which depend on an exact
           implementation of IEEE or ISO rules/specifications for math func-
           tions.

this flag is never safe to use in CFLAGS

no way will our documentation link to gentoo-wiki.com

i find maintaining a list of "safe" CFLAGS on a per-gcc basis to be a waste of 
time ... but that's just me
