Revert "package/ola: fix autoreconf issue for host-ola"

This reverts commit 884af65fd5. Thanks
to the change of the installation path of host-autoconf-archive
macros, host-ola will no longer see them when doing its autoreconf, so
the patch that was added by the commit being reverted here is no
longer needed.

-Subject: [PATCH] autotools: don't overwrite CC and CXX with ACX_PTHREAD
- success
-
-If ACX_PTHREAD sucess, CC and CXX value are overwriten respectively
-to PTHREAD_CC and PTHREAD_CXX. But ACX_PTHREAD has been hacked to
-set PTHREAD_CXX variable for the C++ compiler and configure.ac has
-been modified accordingly.
-
-If ax_pthread.m4 wich provide standard AX_PTHREAD macro (and it's
-alias ACX_PTHREAD and AX_PTHREAD), is installed on the system by
-autoconf-archive package, then ax_pthread.m4 is used during
-autoreconf instread of acx_pthread.m4 bundled with ola.
-
-AX_PTHREAD macro from ax_pthread.m4 check only the thread support
-with the C compiler. As a result, the C++ compiler variable
-PTHREAD_CXX is not initialized, so CXX become empy and the build
-fail during resolv.h check.

-configure:19945: checking for 2-arg pthread_setname_np
-configure:19965:  -o conftest -O2 [snip -I and -L] conftest.cpp  -ldl  >&5
-./configure: line 2037: -o: command not found
-
-In the Buildroot use case, it's safe to remove CC and CXX overwrite
-since only gcc/g++ compiler are used.
