[rfa/rfc] testsuite/gdb.asm without GCC

Hello,
The attatched patch rewrites removes any assumption that there is a
compiler from testsuite/gdb.asm. It instead only tries to use AS and
LD. If you're bringing up a new GDB then often this is all you get.
Thoughts,
Andrew
PS: It affects one target - the d10v.
Tue Jul 4 03:43:49 2000 Andrew Cagney <cagney@b1.cygnus.com>
* gdb.asm/asm-source.exp: Use raw AS/LD instead of CC to
compile/link program.
* gdb.asm/d10v.inc: Define ``startup''.
* gdb.asm/asmsrc1.s: Add definition of _start.
