I think we might need some sort of coordination between the optional
arguments to debugglibc.sh and these arguments to the program being tested.
Otherwise, the position of arguments such as "-e ENVVAR=VALUE" might break
this new use case.
For instance, currently, it doesn't matter if the optional arguments are
passed before or after the path to the test case, so, both:
./debugglibc.sh -b pthread_join nptl/tst-exec1
./debugglibc.sh nptl/tst-exec1 -b pthread_join
With this suggested change, that would no longer work, which is not
necessarily a problem, but caught my attention.
This option, on the other hand, has no conflicts with the current
behavior, but it would need some documentation in the --help message.

Since you already wrote the diff, would you also like to write the commit
message and send it as a patch?
