Summary: A previous patch added a dependency on the stack protectors, this was not built on the GPU targets so every test was disabled. It turns out that disabled tests still get targets so we need to specifically check if the it is in the target's set of entrypoints before we can use it. Another patch, because the build-bot was down, snuck in that prevented the new math tests from being run. The problem is that the `signal.h` header requires target specific definitions but was being used unconditionally. I have made changes that disable building this header if the file is not defined in the config. This required disbaling the signal_to_string utility, so that will simply be missing from targets that don't define it. Fix path Fix on Linux

A previous patch added a dependency on the stack protectors, this was
not built on the GPU targets so every test was disabled. It turns out

Another patch, because the build-bot was down, snuck in that prevented
the new math tests from being run. The problem is that the
signal.h
header requires target specific definitions but was being used
unconditionally. I have made changes that disable building this header
if the file is not defined in the config. This required disbaling the
signal_to_string utility, so that will simply be missing from targets
that don't define it.
