I'm not sure why I don't see the same behavior in my setting, but I used
make -p and you're correct, $(dir ...) leaves the trailing slashes.

I've used the approach you suggested yesterday over IRC which simplifies
the Makefile a bit.

I've expanded the check to cover both the existing file and symlink case.

I've been using the previous version in my setup for about two weeks now
and haven't found any further issue but I'd like to hear from others if
they found any issues.

Subject: [PATCH] support out-of-tree build
this change add support for building musl outside of the source
tree. the implementation is similar to autotools where running
configure in a different folder creates config.mak in the current
working directory and symlinks the makefile, which contains the
logic for creating all necessary directories and resolving paths
relative to the source directory.
to support both in-tree and out-of-tree builds with implicit make
rules, all object files are now placed into a separate directory.
