Clean build with JIT fails at stage 2.

[Ed Smith-Rowland]

I wanted to try out gcc-jit on my x86_64-linux box:
I started with a completely empty build directory.
Configure;
ed@bad-horse:~/obj$ ../gcc/configure --prefix=/home/ed/bin --enable-lto 
--enable-languages=c,c++,fortran,go,jit,lto,objc,obj-c++

Let me know if there is some other configuration product I should attach.

The build stops in stage 2 with:
