Remove PTHREADS_ASSIGN_VARS

This simplifies TSRM build steps a bit and avoids doing unnecessary
steps:
- The `PTHREADS_CHECK_COMPILE` can called inside the for loops only
  since this is only where the `$pthreads_checked` variable is used.
- Assigning variables can be then done only in the configure.ac
  once.
- use `m4_include()` instead of the `sinclude()` in the middle of
  the build steps.
- The `$threads_result` variable is not used in the code or in
  extensions.
