You might be able to use:

 PATH_WORKAROUND = `relpath $(abs_top_builddir)/Tests/some_file.foo`

But then you must be aware that $(PATH_WORKAROUND) cannot be used
as a file at make level (i.e., can't be a prerequisite, or a target,
and so on), and can only be used as a shorthand in the shell code
of your recipes.
