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.
