[PATCH] Revert to using target_link ind gdb.asm/asm-source.exp

[Mark Kettenis <kettenis@chello.nl>]

We have been discussing this repeatedly over the past two years.  The
consensus was that using gcc to do the final link isn't appropriate
for this test.  This effectively reverts the change made by Corinna in
december 2001, and will probably break the ARM and similar processors.
Adding the right defenitions to the board defenition seems the only
true way to solve the problems.

If nobody objects, I'll commit this next week or so.

	* gdb.asm/asm-source.exp: Strip -Wl, from link-flags.  Don't
	append -static to link-flags for *-*-freebsd*, *-*netbsd* and
	*-*solaris2*.  Remove commented out default settings for
	asm-flags.  Replace gdb_compile with target_link.
