ci: add clang permutation, for 64bit only

Throw clang into the matrix, so we get a bit of extra coverage. As
evidenced by the disabled warning - it does catch extra issues.

Currently enabled only for 64bit builds, since fiddling with environment
variables and cross-files is more tricky than I can be asked atm x-D
