libstdc++, Darwin: Do not use dev/null as the file for executables.
Darwin has a separate debug linker, which is invoked when the command
line contains source files and debug is enabled.
Using /dev/null as the executable name does not, therefore, work when
debug is enabled, since the debug linker does not accept /dev/null as
a valid executable name.
The leads to incorrectly UNSUPPORTED testcases because of the unintended
error result from the test compilation.
The solution here is to use a temporary file that is deleted at the
end of the test (which is the mechanism used elsewhere)
libstdc++-v3/ChangeLog:
* testsuite/lib/libstdc++.exp (v3_target_compile): Instead of
/dev/null, use a temporary file for test executables on Darwin.
