Handle tests-unsupported if run-built-tests = no.
The tests-unsupported variable lists tests that should neither be compiled nor run, because some support needed to compile them is missing. The implementation of this feature involves having a rule to create .out files for these tests that takes precedence over the default rule. This does not work in the run-built-tests = no case (cross compiling without use of a wrapper to run the tests on a separate system, in which cases most tests are compiled only) because in that case the tests target depends on $(tests) to ensure all tests get compiled. This patch changes that dependency to filter out $(tests-unsupported). Tested with cross-compilation to ARM with GCC 5, where libstdc++ is missing some C++11 support because of the bug I fixed in <https://gcc.gnu.org/ml/gcc-patches/2015-10/msg01040.html> and so tests-unsupported is nonempty and the tests in question fail to compile. (When I originally observed the bug, it was with a native build / test simply using an x86_64 compiler that had been configured as a cross compiler to isolate it from the system headers / libraries, so the configuration issue applied to the compiler but run-built-tests was yes, so I don't observe the issue with tests-unsupported with that compiler.) * Rules [$(run-built-tests) = no] (tests): Do not depend on $(tests-unsupported).
