Subject: [PATCH 17/21] Fix configuration when `EMSCRIPTEN_ROOT` is an absolute
 path

Not sure whether this is unusual but under Arch Linux the `emscripten`
package specifies absoute paths in `/usr/lib/emscripten/.emscripten`. In
this case it makes no sense to treat them as relative to `EMSDK` (which
would lead to configuration errors).
