Link with rt library to get clock_gettime where necessary
Issue #450 (bdwgc).
This patch adds the logic to CMake and configure scripts to pass -lrt
option during linking to avoid unresolved clock_gettime on some hosts.
* CMakeLists.txt [!NEED_LIB_RT] (HAVE_CLOCK_GETTIME_DIRECTLY): Set
variable by check_function_exists(clock_gettime).
* CMakeLists.txt [!NEED_LIB_RT && !HAVE_CLOCK_GETTIME_DIRECTLY]
(NEED_LIB_RT): Set to ON.
* CMakeLists.txt (LIBRT): Refine comment.
* CMakeLists.txt (gc): Specify target_link_libraries regardless of
enable_threads.
* Makefile.am (libgc_la_LIBADD): Update comment.
* configure.ac (need_lib_rt): Define variable (and set to false).
* configure.ac [$THREADS==pthreads && ($host==*-*-hpux11*
|| $host==*-*-netbsd* || $host== *-*-solaris* || $host==*-*-osf*)]
(THREADDLLIBS): Do not add "-lrt" directly.
* configure.ac [$THREADS==pthreads && ($host==*-*-hpux11*
|| $host==*-*-netbsd* || $host== *-*-solaris* || $host==*-*-osf*)]
(need_lib_rt): Set to true.
* configure.ac [!need_lib_rt && !AC_LINK_IFELSE(clock_gettime)
&& AC_CHECK_LIB(rt,clock_gettime)] (need_lib_rt): Set to true.
* configure.ac [need_lib_rt] (THREADDLLIBS): Append "-lrt".
