auto merge of #11963 : alexcrichton/rust/fix-rustpkg, r=brson

Browse source 
Right now the bots are all injecting a libstd version, so all the rustpkg tests
are passing. All rustpkg compilations will fail unless the version number is
explicitly given because rustpkg attempts to exactly guess the target file name.
Switch back to using a pattern match in order to unbreak tests.

Closes #11852
