OMG ... who put that utter nonsense into CFLAGS? Is that the
default configuration of Gentoo nowadays? I'm shocked. Try this:

  make clean; make CFLAGS=

Simply said: you can't expect to compile a majority of C libraries
with these flags. Esp. -fwhole-program is deadly for shared
libraries that are *supposed* to export functions.

In other words: consider using a saner distro than Gentoo. It does
not live up to its promise. And that has been true for a looong
time. I think I stopped using it 7 years ago and never looked back.
