In #51456, @qmx and I noticed that compiletest, when using aux-build libraries, simply supplies the compiler with -L instead of using the --extern lib_name=path-to-rlib compiler argument form. This is a shame because the latter form is what cargo actually uses in practice!
We ought to add another comment form to use the latter. Something like:
// aux-build:lib_name=file.rs
or perhaps a different header name.
(We could also retrofit the existing aux-build to use --extern, but it seems useful to be able to test in both modes, actually, so I'd prefer to add something new.)
