Revert "autotools: try improving thread detection."
This reverts commit 14c6378fc41906db14464e17aadc7d94a825fafd. So either we get to fix https://phab.enlightenment.org/T880 or https://phab.enlightenment.org/T986. I do think the problem is more tricky than that, so I am for the moment going to get https://phab.enlightenment.org/T880 broken rather than https://phab.enlightenment.org/T986 as I think the later will show up in more case for our user base. Will try to find a proper solution for everyone before the next release.

-# SYNOPSIS
-#
-# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
-#
-# DESCRIPTION
-#
-# This macro figures out how to build C programs using POSIX threads. It
-# sets the PTHREAD_LIBS output variable to the threads library and linker
-# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
-# flags that are needed. (The user can also force certain compiler
-# flags/libs to be tested by setting these environment variables.)
-#
-# Also sets PTHREAD_CC to any special C compiler that is needed for
-# multi-threaded programs (defaults to the value of CC otherwise). (This
-# is necessary on AIX to use the special cc_r compiler alias.)
-#
-# NOTE: You are assumed to not only compile your program with these flags,
-# but also link it with them as well. e.g. you should link with
-# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
-#
-# If you are only building threads programs, you may wish to use these
-# variables in your default LIBS, CFLAGS, and CC:
-#
-# LIBS="$PTHREAD_LIBS $LIBS"
-# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-# CC="$PTHREAD_CC"
-#
-# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
-# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
-# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-#
-# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
-# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
-# PTHREAD_CFLAGS.
-#
-# ACTION-IF-FOUND is a list of shell commands to run if a threads library
-# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
-# is not found. If ACTION-IF-FOUND is not specified, the default action
-# will define HAVE_PTHREAD.
-#
-# Please let the authors know if this macro fails on any platform, or if
-# you have any other suggestions or comments. This macro was based on work
-# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
-# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
-# Alejandro Forero Cuervo to the autoconf macro repository. We are also
-# grateful for the helpful feedback of numerous users.
