No. That is, I'm willing but apparently not able.

GDB didn't seem to offer up much. It was able to find getcwd (after 
loading shared libraries) and set the breakpoint but it would exit out 
(still with error code 7) before reaching the break. After looking 
through test-getcwd.c, though, I don't know how that's possible. I can 
say for sure that when GDB was setting the breakpoint, it was finding 
libc's getcwd, not GNUlib's (based on its address).

Hopefully, this qualifies: Because I was unable to get anything else out 
of GDB (that was literally my first time ever using the program), I 
resorted to directly editing test-getcwd.c a few times and determined 
that errno gets set to ENOENT before triggering the failure.
