tests: include test declarations for old gcc Older versions of gcc do not believe that we've adequately declared our test functions. Include `clar_suite.h` conditionally for those old versions. Do not do this on newer compilers to avoid unnecessary recompilation of the entire suite when we add or remove a test function.
