dejagnu: ensure 'srcdir' is defined as a relative directory This change fixes automake bug#7833. * lib/am/dejagnu.am (check-DEJAGNU): Prefer using plain $(srcdir) over calculating and using the absolute path of $(srcdir). * tests/dejagnu-relative-srcdir.test: New test. * tests/dejagnu-absolute-builddir.test: Likewise. * tests/Makefile.am (TESTS): Update.
