Hi.
I verified this patch works by successfully compiling sparc GCC (just the
compiler, not the libraries) on my x86_64 linux machine. I didn't try
bootstraping nor regtesting since I don't have a sparc machine readily
available and since it doesn't seem relevant for this patch.
Configured with (though the --disable-multilib and --disable-libsanitizer
shouldn't matter):
--target=sparc-linux --disable-multilib --disable-libsanitizer
--disable-bootstrap
Ok to push?
Thanks,
Filip Kastl

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.

* config/sparc/sparc.h (TARGET_TLS): Use '#ifdef HAVE_AS_TLS ...
#define TARGET_TLS 1' instead of '#define TARGET_TLS HAVE_AS_TLS'.
