tar: set acpaths to avoid "Argument list too long" error

There would be an error when the TMPDIR is long/deep, for example when
len(TMPDIR) = 410 while our supported longest value is 410:

    aclocal: error: cannot open xxx
    autoreconf: aclocal failed with exit status: 1
    ERROR: autoreconf execution failed.

Let aclocal use the relative path for the m4 file rather than the
absolute would fix the problem.
