libstdc++: Add a test for <version> FTM redefinitions
This test detects redefinitions by compiling stdc++.h and <version>, by
disabling the system_header pragma on the latter, to allow warnings in
it. Thanks Patrick Palka for the suggestion.
libstdc++-v3/ChangeLog:
* testsuite/17_intro/versionconflict.cc: New test.
* include/std/version: Allow disabling the system_header pragma
via _GLIBCXX_TESTING_SYSHDR.
