Fix TestRegisterVariables for linux arm/arm64 gcc ver > 5

Authored by omjavaid on Jan 13 2017, 1:32 AM.



TestRegisterVariables fails with O1 level when using gcc version 5.0 or above on arm/arm64 linux targets.

The reason is injection of buffer overflow protection code at O level 1. This patch turns off buffer overflow protection code by turning off FORTIFY_SOURCE.

Can we commit this if nothing goes wrong on any other target. ?

Seems reasonable. Maybe add a comment explaining why is that macro defined.

This test is incredibly brittle. I think we should find a better way to test the feature, but I don't really have a good idea so far...
