When we install the ObjFW port there's a few issues:

• It does not list llvm as a required dependency
• The installed scripts, objfw-compile, objfw-embed and objfw-config are prefixed with x86_64-pc-serenity- which is a bit awkward for what will be a native compiler on the target.
• The objfw-config script lists OBJCC as x86_64-pc-serenity-clang, which is not what the installed port of Clang will be on the target (it's just /usr/local/bin/clang as installed)

This is probably(?) because we compile it with x86_64-pc-serenity-clang on the host, but that doesn't line up with what the environment will be at runtime.

The scripts also use if !, which is not supported by /bin/Shell --posix, but Ali mentioned to me on discord that he was already looking at that one as a bug report to Shell.
