Check stdout macro for FILE.
As all C standards to date require stdout to be declared as a macro in
stdio.h, this should be the most portable way to check whether we can use
the FILE type. This change was made to get GMP running on the Sortix
operating system.
The preëxisting checks were left as-is to not break compatibility on other
platforms, but can be removed if a standards-compliant C implementation is
required.
