ts_run: Don't run make:all/1 without a good reason
ts:run() runs make:all/1 to facilitate interactive development of a test suite - when you have changed your test suite, just run ts:run() and it will rebuild the test suite for you. Some test suites, such as for the public_key application, are meant to be built once and for all by "make release_tests". Re-building it later with make:all/1 will fail because it references an internal .hrl file in the source directory for public_key. Running make:all/1 for the public_key test suite would not cause any harm in most circumstances, because make:all/1 would consider the *.beam files to be up-to-date and therefore not actually try to re-build anything. In 2c6d9b57ce4557a431bcf02565c3634a0ed7ca61, however, the public_key test suite started to include "test_server.hrl" using -include_lib() instead of -include(). That means that "test_server.hrl" will be included from the Erlang/OTP system being tested, and if that system has been built *after* the test suite was built, the *.beam files in the test suite will be out-of-date and make:all/1 will try to re-build them (and fail). To avoid this problem, modify ts:run() as follows: * If the test suite has an Emakefile (such as the emulator test suite), it is clearly meant to be (re-)built by make:all/1, so we run make:all/1. * If there is no Emakefile and no .beam files (such as in the erl_interface test suite), it also seems clear that the test suite is meant to be built by make:all/1. To make sure that the test suite will also be *re-built*, create an Emakefile that will re-build all *.erl files in the directory for the test suite. * If there is no Emakefile and there are *.beam files (such as for the public_key test suite), we assume that the test suite are not meant to re-built. However, there may be generated *_SUITE_make.erl files (if there are *_SUITE_data directories containg Makefile.src files, as in the xmerl application). If there are any *_SUITE_make.erl files, generate an Emakefile for compiling only those files and run make:all/1. Otherwise, don't run make:all/1.
