 clang-17,18: disable verbose_abort in availability

 when availability tests are disabled (macports-libcxx, darwin 10)
 a fallback set of defines are used in

 include/c++/v1/__availability

 however, the fallback defaults to indicating that libcxx contains
 a verbose_abort function. This is currently always false for MacPorts
 uses, and so link errors occur.

 disable this by default, so a fallback pathway is used

 see: https://trac.macports.org/ticket/68640

 this has no effect on the normal functionality of this header,
 as the __APPLE__ pathway is used otherwise.
