[configure.ac] Reverted r14572, which was solving an issue about the

ordering of macros with ax_pthread.m4 29.

But the change done in ax_pthread.m4 29

was incorrect (see comments at this URL) and was reverted in
ax_pthread.m4 31:
  https://github.com/autoconf-archive/autoconf-archive/commit/59008cc7f85e1982eb298e1c424c2e6ad5942c4a
(Debian/unstable had the buggy version during a couple of weeks).

-dnl So we need to call AC_CANONICAL_TARGET here, even if we don't use it.
