The configuration MBEDTLS_MEMORY_BACKTRACE is intended for debug and
is not necessary for test coverage. Because it causes timing problems
in some tests the configuration has been removed as it's not present in
equivalent tests in the all.sh test script.
Previously the test worked on the default configuration which missed deprecated
or legacy features. This change tests the full configuration and all available
tests.
Following fixes:
* In the test script, 'basic-build-test.sh', the total number of functions had
a broken RE, and was picking up the number of tested functions.
* Titles of tests was misleading
* The 'run-test-suites.pl' script was mistaking dSYM directories as test
suites to be executed.
