Yes that is because the other tools run autom4te from Autoconf under the
hood.

Can you install a recent-enough Autoconf under another prefix, or maybe
with --program-suffix=-2.62, and set the variables accordingly, e.g.,
  AUTOCONF=autoconf-2.62 AUTOM4TE=autom4te-2.62 \
  AUTOHEADER=autoheader-2.62 autoreconf

?  Another possibility is to put all generated files under version
control (until GCC has been updated to newer autotools as well).

Cheers,
Ralf
