Subject: Fixes unused argument warnings in config.log.

The test programs used for some of the configure checks use dummy
main() functions which ignore argc and argv.  Adding void casts keeps
these from giving warnings in config.log.

TESTED:
Build still works, and relevant warnings in config.log are gone.
