Go through both run_make_tests.pl and test_driver.pl and slightly modernize the Perl and clean up indentation etc. Fix a number of warnings in the test scripts detected by running with -w. * tests/test_driver.pl: Move make error string detection out of the base test driver. (run_all_tests): Ensure that we always look for tests in the cwd. * tests/run_make_tests.pl: Use File::Spec for path manipulations. Correctly use setlocale() when detecting error strings. Get configuration from the config-flags.pm file not config.status. * tests/scripts/features/archives: Use new $cwddir variable. * tests/scripts/features/reinvoke: Add missing semicolon. * tests/scripts/features/vpath2: Avoid non-existent variable. * tests/scripts/functions/foreach: Escape variables. * tests/scripts/misc/bs-nl: Remove non-existing \v escape sequence. * tests/scripts/misc/general4: Use handy create_file(). * tests/scripts/options/dash-C: Use Cwd/$cwddir. * tests/scripts/options/dash-I: Use subst_make_string() and #PWD#. * tests/scripts/options/symlinks: Use File::Spec. * tests/scripts/targets/DEFAULT: Use create_file and run_make_test. * tests/scripts/variables/CURDIR: Use run_make_test. * tests/scripts/variables/automatic: Remove extraneous "\". * tests/scripts/vms/library: Remove extra "my" and extraneous "\".
