toolchain-funcs.eclass: Add tc-has-64bit-time_t
Add a helper function to check whether time_t is 64-bit. This could
be used e.g. to deselect tests that rely on timestamps exceeding Y2k38.
It is meant to be more future-proof than hardcoding a list of 32-bit
architectures, given the necessity of switching to 64-bit time_t
in the future.
