Thank you for the patch.  I wasn't aware of this code at all :-)

I wonder if it would make sense to instead set gdb_wrapper_file to the
absolute path.

It could perhaps be put in the cache directory.  This might help avoid
recompiling it many times when running the tests in parallel.

What do you think of that?

GNU style is to start a comment with an upper-case letter, so "If".

If you don't like the absolute path idea, maybe just having all this
logic be in the wrapper code would be better, and this could just call
gdb_wrapper_init unconditionally.
