I'm glad you had some success. However, I found I needed the
"--with-newlib" in order to build gcc. I also removed the installation
of the glibc-headers, you should too especially since you're using
uClibc. From what I've read, --with-newlib cause gcc to build against
newlib (as a libc replacement), but --without-headers instructs gcc to
not look for newlib headers. All other configurations seem to require
some piece of a libc without being able to compile a libc.
This is what my gcc_static build stage looks like, keep in mind I am
using glibc, and not uClibc.
