[PATCH] Fix --directory handling

[Tom Tromey]

I noticed while working on gdb that --directory handling doesn't work.
The problem is that with something like "--directory=gdb.gdb", [string
match] will not return true for the cases it is given.  Instead
matching "*/$directory" is needed when the srcdir is provided.

* runtest.exp: Fix --directory matching.
