Can you not pass the correct -install_name=$PREFIX/lib/libsomething.dylib flag
when you link it, and thus avoid needing to use install_name_tool later?

The build phase is supposed to build the software, including building the
libraries with the install_name set to where the files will ultimately be
installed in $PREFIX.
The destroot phase is supposed to copy the files from the build directories to
the correct layout in the destroot directory. Ideally the destroot phase should
not need to use install_name_tool or modify the files in any other way, just
copy them to where they need to go.
