Cross compiling shouldn't require a C compiler unless you have a dependency on C code.

Most wrappers should at least provide an option to statically link the C; I know the OpenSSL ones do.

Not a C compiler, but you need a C linker, which is just as much hassle. Apparently there is work going on to use LLVM's lld linker, which I guess might support cross-compiling in a sane way but I haven't checked.

And yeah most wrappers provide a static linking option but there's not much consistency which is rather annoying.
