The file is not corrupted, and the file content is not changed,  "tar"
said xorg-macros.m4 file is changed, since the number of links of
xorg-macros.m4 has changed when other packages is doing configuration
and call autotools_copy_aclocal to make a hardlink to ${ACLOCALDIR}

If this fix can be accepted, I will rework the commit header.
