I am trying to cross-compile gcc 4.7.2.
configure --host=$HOST --target=$TARGET --prefix=/usr --enable-languages=c,c++
--without-headers --disable-bootstrap
The build fails when building stage1 libgcc with this error

gcc tries to include/link the target libc. I have not build that as I do not
have a working cross compiler. What am I missing?
