build: fix introspection interpreter issue when project selects RustHEADmaster

The introspection interpreter sometimes produces targets with no source
files; BuildTarget will then pick a random compiler, according to the
order in clink_langs.

According to the comment in sort_clink, clink_langs are supposed
to list languages from *lowest* to highest priority.  However,
process_compilers_late() process clink_langs in straight order and
returns the first language; which is the one with lowest priority.

This became visible with the addition of Rust to clink_langs,
because Rust has limitation on the names of library targets, but
the bug existed before.
