libstdc++-v3:
* tests_flags.in: New file. Split out of ...
* mkcheck.in: ... this. Move flags computation into
tests_flags.in.
* configure.in: Add support for tests_flags.
* confiigure: Regenerate.
gcc/testsuite:
* lib/g++.exp (g++_include_flags): Invoke 'tests_flags --compiler'
instead of 'mkcheck 2'.
