[PATCH v2 1/3] valgrind: let valgrind determine its own optimisation flags

[Andre McCurdy <armccurdy@gmail.com>]

Valgrind likes to control its own optimisation flags. It generally
defaults to -O2 but uses -O0 for some specific test apps etc. Passing
our own flags (via CFLAGS) means we interfere with that.

Giving valgrind control of optimisation is hopefully an even better
solution than the previous one of forcing -O0 for all tests.
