This can be fixed by setting LD_LIBRARY_PATH to the build directory in
the all rule in Makefile.in but I don't know if this is correct fix. As
things stand, the dlopen command loads the installed version of libc.c
instead of the newly built version.

Probably the test should be run in the container.
