Alright, here's a revised patch. I've once again verified that the x86_64
host, sparc target crosscompiler builds.

Since r16-6798, it wasn't possible to build a sparc GCC without having
a sparc assembler installed. That shoudn't be the case since there are
usecases for just compiling into assembly.
The problem was sparc.h doing '#define TARGET_TLS HAVE_AS_TLS'.
Building GCC failed when HAVE_AS_TLS wasn't defined which is the case
when one doesn't have an assembler with TLS installed during
./configure.
This patch addresses the problem.
