This still turns up in 4.6 trunk downloaded from yesterday. doing a make
all-gcc fixes the problem.

Building a cross compiler is complex unless you already have a sysroot.

Using an semi-supported script from say crosstoolng is better idea.

Plus I build cross toolchains all the time with different source bases.

--- Comment #8 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Much more importantly, gcc-core doesn't exist anymore (so WORKSFORME is a
strange resolution).

Using the documented build procedures is recommended, and is what is
supported here (not any cross tool whatever thing).

I obtain a similar error message when building a gcc-4.5.0 cross compiler:

I used full gcc sources, not gcc-core. I also managed to find a workaround to
this problem, that is, adding --disable-libgomp to the configure argument list.
