autotools.bbclass: using relative paths for acpaths

Fix autotools.bbclass to use relative paths for acpaths instead of
absolute ones. Since absolute paths may cause potential autoreconf
error like:

    Can't exec "/bin/sh": Argument list too long ...

This error occurs while building coreutils with long TMPDIR, because
it has bunch of m4 files need to be expanded.
