cryptlib @3.4.5: Build fails due to undefined _Static_assert

[ryandesign (Ryan Carsten Schmidt)]

cryptlib forces the use of clang and assumes it supports _Static_assert; the ancient version on Snow Leopard ​apparently does not.

[kencu (Ken)]

This doesn't happen any more, now that 10.6.8 defaults to clang-9.0.

However, build still fails because the clang-9.0 on 10.6.8 has the sanitzers disabled:

I get this error on 10.6 PPC with gcc11:

[kencu (Ken)]

see ​https://trac.macports.org/ticket/64427#comment:10 for ideas on how to solve this.

putting a fix for assert.h into legacysupport might be the best path.
