	* Makefile.am (SUBDIRS): Add testsuite
	* configure.ac (AC_CONFIG_FILES): Removed.
	(AC_OUTPUT): Add Makefile testsuite/Makefile
	po/Makefile.in:po/Make-in.
	(AM_CONDITIONAL): Add NATIVE.
	* Makefile.in: Regenerated.
	* configure: Likewise.
	* testsuite/Makefile.am: New file.
	* testsuite/tst-gmon-gprof.sh: Likewise.
	* testsuite/tst-gmon.c: Likewise.
	* testsuite/Makefile.in: Generated.
