All right!  This patch is approved.

Then the test can continue to FAIL until someone files a bug report
for it, or just fixes it, or maybe makes it UNSUPPORTED.  That's okay.

Err right, my sample code was bad.  Yeah, it's okay to just test
asm-source.exp.

Beautiful, that's what I'm looking for.

Now the next poor hacker who ventures into asm-source.exp will have
something to read when they say "what is this ... let me check the
mailing list archives ...".

	* gdb.asm/asm-source.exp (debug-flags): New variable.  If a
	known good default value for a specific architecture is
	available then set it to that value.  Otherwise default to the
	-gstabs switch.  Remove the -g... switches from the asm-flags
	variable.  Allow the target board info to override the value if
	it wants to.  Pass the switch on the assembler command line.
