Makefile: Fix linker error

Browse Source 
Instantiation of the static singleton instance thermalManager in general
requires locking, but we know its safe to do without.

Add -fno-threadsafe-statics to avoid using locking primitives, which
result in linking errors:
	undefined reference to `__cxa_guard_acquire'
	undefined reference to `__cxa_guard_release'
