* testsuite/27_io/*.cc: Remove explicit reference to 'testsuite/'
in testcases. Prepare for the DejaGnu based framework.
* mkcheck.in: Adjust call to tests_flags. Don't mmkdir testsuite
directory -- it is now mkcheck working directory.
* tests_flags.in: Remove reference to $(top_srcdir). Use
${SRC_DIR} instead.
* Makefile.am (check, check-install): Change mkcheck invocation
logic.
* Makefile.in: Regenerate.
