Well, at this point I am not interested in any particular target. I am
interested in having uClibc building a correct toolchain, that doesn't
contain headers describing functions that it doesn't implement, causing
build issues in various userspace packages.

So I guess we should simply disable the possibility of enabling fenv
support on those architectures that don't have the necessary code.
