FYI: convert gdb.asm

I'm checking this in.

This converts gdb.asm to use the new test suite procs.

It also fixes a bug where gdb.asm built the object files directly in
".".  This is wrong because it can cause hidden parallelization bugs,
should any other test case happen to use the same file names.  (Unlikely
in this instance, but still.)

Regtested on x86-64 Fedora 16.

	* gdb.asm/asm-source.exp: Use standard_output_file,
	standard_testfile.  Construct .o files in proper subdir.
