[Buildroot] RC3 ctng toolchain build failure

[Chris Kerios]

Doing a vanilla build (nothing other than defaults) on Fedora 14 host
for a i386/geode target.  No packages added, just brought up make
xconfig and set for ctng with uclibc for the library and saved.  No
other settings  were used other than defaults for everything.  Was not
using ccache either.  Seems it can't find fenv.h for some reason.
Researched news list and didn't see anything on this except something
a few months ago about version conflicts and not using ccache.  Also,
I didn't select to build C++ either.  Any ideas?  Messages below.

Regards,
Chris
