Configure is as follow:

/new-system being the sysroot dir used by gcc and where target glibc headers
are. Adding "-I/usr/include" also works even if wrong header is picked this

As a side note changing the "C" header model from c_global to c_std in
libstdc++-v3/configure.host file solves the problem as fenv.h is no longer
installed by gcc along with three other headers (two of them being also
provided by glibc).
Thanks for your time.
