The problem, illustrated, was covered earlier in this thread. In summary:
If I am building a project using the GNU auto tools (automake, autoconf and 
libtool) it produces a script that will work with libraries that are in my 
compile directories, but not yet installed. I must invoke gdb as:
libtool gdb <exec target>

emacs injects parameters to the command line I provide so that it reads 
something like
libtool -cd <working dir> gdb <exec target>

which, when invoked in the context of libtool, makes no sense and gdb fails to 
start. However, if it is invoked as
libtool gdb <exec target> -cd <working dir>
gdb is happy and I can debug my uninstalled executable (wrapped by the libtool 
generated script). I've wrapped the libtoo/gdb invocation in a script (per a 
suggestion posted immediatly in response to my question) and that is an 
acceptable workaround for me.

Ideally, I would like to just feed the exec target to emacs and have it do the 
right thing. In practice, it would be nice if I *have* to prefix gdb with 
libtool, if emacs would append it's arguments to my command line rather than 
insert them before the second argument on the command line.

I offered a patch a while ago when I ran into this problem, but someone said it 
was already fixed in CVS, so I'll just wait until it's released and gentoo 
packages are ready. I can live with the workaround until then.

Thanks to everyone on the mailing list who have been so responsive and helpful!
