[FYI] {testsuite-work} tests: few more checks on automatic remake support

[Stefano Lattarini]

* tests/remake-all-1.test: New test, check that the "all" target
triggers rebuilt of outdated Makefiles.
* tests/remake-all-2.test: Likewise, but for when the makefiles
are not named `Makefile'.
* tests/Makefile.am (TESTS): Update.

        tests: check some remake features with non-GNU make too
        * tests/acloca14.test ($required): Drop "GNUmake".  This test
        works as-is with non-GNU make implementations.
