Support freestanding. (at_quick_exit, quick_exit): Add using directives. * include/c_global/cmath: Use #include_next for math.h. * include/c_global/cstdlib: Use #include_next for stdlib.h. * testsuite/26_numerics/headers/cmath/14608.cc: New. * testsuite/26_numerics/headers/cmath/c99_classification_macros_c.cc: Remove xfail for most targets. * testsuite/26_numerics/headers/cstdlib/60401.cc: New.
