libstdc++: Fix deleted overload of __absu(bool)
libstdc++-v3/ChangeLog:
* include/std/numeric (__detail::__absu(bool)): Make deleted
function a function template, so it will be chosen for calls
with an explicit template argument list.
* testsuite/26_numerics/gcd/gcd_neg.cc: Add dg-prune-output.
* testsuite/26_numerics/lcm/lcm_neg.cc: Likewise.
