If they are not completely supported, the libc shouldn't generate
them (to avoid FPE signals when results of libc functions are used
in input of other operations).

I completely disagree. I care about the C standard, and I explicitely
say so with the -std=c99 option. Perhaps things like -std=c99 should
imply -mieee then, if no change is done in glibc (and __STDC__
shouldn't be defined if no such option is used).
