Several Cargo-based ebuilds cannot use cargo_src_install for various
reasons and manually install binaries from within the target directory
instead. It is common to see `target/$(usex debug debug release)`, but
this lacks the target ABI when cross-compiling, so provide a helper
function.
There are some multilib Cargo-based ebuilds that always set the target
ABI, even when not cross-compiling. It would be simpler to do this in
general, so once ebuilds have been updated to use this new helper, I
might change the eclass again accordingly.
