Else, links to `char::foo` would point into `/path/to/src/libcore/std/primitive.char.html#method.foo`.

Split out from rust-lang#73804.

They both produce less-than-desirable output (links going to docs.rust-lang.org), but I haven't figured out yet how to assert about them properly.

For the two of these tests that have a local `char` to link to, this behavior isn't what's expected, but is what's happening presently.

This reverts commit ee3a0f8.

This pulls in a fix for the install script on some tr(1) implementations,
as well as an update to use `anyhow` instead of `failure` for error
handling.

Keep congruency with other parts, full word vector is rarely used.

adjust ub-enum test to be endianess-independent

@cuviper noted that our test fails on "other" endianess systems (I never know which is which^^), so let's fix that.

Use relative path for local links to primitives
