Probe the target system for needed headers
This prevents new or unconventional systems requiring upstream changes,
though, this is not perfect, as it doesn't address some of the other
defines related to OSes the preprocessor does (namely, wrt the ldso
cache handling). I didn't touch these yet as I took a more conservative
approach of (probably) not changing what happens at runtime.
