Now loongarch.md uses HAVE_AS_TLS, we need this to fix the failure
building a cross compiler if the cross assembler is not installed yet.
gcc/ChangeLog:
* config/loongarch/loongarch-opts.h (HAVE_AS_TLS): Define to 0
if not defined yet.

Ok for trunk?
I have no problem with this submission, but I don't understand the
circumstances surrounding the error.
When the developers hack GCC they sometimes build a cross compiler with
no cross assembler, then HAVE_AS_TLS will just be undefined. And in the
future we may have an assmebler w/o TLS support (for example a tiny
assembler for bare-metal target), then HAVE_AS_TLS will be undefined
too.
Ok!
Thanks!
