Subject: [PATCH] Revert "AX_PTHREAD: target > host"
This reverts commit 2567e0ce0f3a11b535c6b527386197fb49ff172b.
* `AC_CANONICAL_HOST` is the system on which the actual binary will run,
`AC_CANONICAL_TARGET` is the system for which code is generated. The
Autoconf manual even mentions that
--target=target-type
the type of system for which any compiler tools in the package produce code (**rarely needed**).
