Replace thread config with automatic config using ax_pthread.m4.
The autotools library macro (AX_PTHREAD) is now used to detect if
pthreads is present and multi-threaded linking in gold is automatically
enabled if it is found. This enables multi-threaded gold on platforms
where pthreads is enabled via other methods than just -lpthread
(e.g., MinGW).

(THREADSLIB): Remove; change all references to THREADLIBS.
* Makefile.in: Regenerate.
* aclocal.m4: Regenerate.
* config.in: Regenerate.
* configure: Regenerate.
* testsuite/Makefile.am (THREADSLIB): Replace with...
(THREADFLAGS, THREADLIBS): ... these.
(LDADD): Remove; add as individual defines for...
(object_unittest, binary_unittest, leb128_unittest)
(overflow_unittest): ... these tests.
(tls_test, tls_pic_test, tls_pie_test, tls_pie_pic_test)
(tls_shared_test, tls_shared_ie_test, tls_shared_gd_to_ie_test)
(tls_shared_gnu2_gd_to_ie_test, tls_shared_gnu2_test_LDFLAGS)
