1 - Look at testsuite.h, struct test, to see all the options available.
2 - Fill in the name and description. Convention is to have the name equal to
the function used to test and the struct name as s<function-name>
2 - Use TESTSUITE_MAIN and DEFINE_TEST to add new tests. Don't forget to fill
its description.
3 - If you want testsuite to compare the stdout/stderr of your tests in order
to check if it worked or not, fill in output.{stderr,stdout} the file with the
expected output. Bare in mind the same file is used for all architectures, so
don't print arch-dependent content if you are comparing the output.

4 - Fill in the config vector. Setting any of these configuration will make
testsuite to export LD_PRELOAD with the necessary override libs before
executing the test. If you are not exec'ing an external binary, you need to
pass "need_spawn = true" below, otherwise it will not work (LD_PRELOAD is only
applied when exec'ing a binary). See each config description in testsuite.h

7 - If you added files to the rootfs, be sure to compact it back to
rootfs.tar.xz before sending patches.

8 - Tests can be run individually, outside of 'make check'. strace and gdb work
too, as long as you tell them to operate on child process.
