Update.
* dlfcn/Makefile (distribute): Add glreflib1.c and glreflib2.c. (tests): Add glrefmain. Add rules to build modules and run tests. Ignore result of glrefmain for now since it fails. * dlfcn/glrefmain.c: New file. * dlfcn/glreflib1.c: New file. * dlfcn/glreflib2.c: New file. * test-skeleton.c: Include <string.h> for strsignal prototype.
