Introduce mechanism to check standard conformance of headers

While pretty simplistic, it appears to serve the purpose at the moment
(i.e. it spotted two places where a GNU extension was used withou
proper preprocessor conditionals). The "simplistic" here includes that
the checking gets only done for native builds, and ia64 gets excluded
due to its arch-specific header intentionally (for whatever reason)
checking that anonymous struct/unions can be used.
