It didn't.  It removed support for the SPE vector extensions only.

It works in powerpc*-*-linux* the same as it always has.  If you try
to build GCC for a powerpc*-*-*spe* configuration it will tell you
that is unsupported, to prevent surprises (it would just use a non-SPE
config, otherwise, not likely what a user wants).

In glibc, e500 might be pretty much equal to SPE, of course.  But for
GCC it is not -- it is just another CPU.
