gccgo: link static libgo against -lrt on GNU/Linux
The upcoming Go 1.18 release requires linking against -lrt on GNU/Linux (only) in order to call timer_create and friends. Also change gotools to link the runtime test against -lrt. * gospec.cc (RTLIB, RT_LIBRARY): Define. (lang_specific_driver): Add -lrt if linking statically on GNU/Linux. * configure.ac (RT_LIBS): Define. * Makefile.am (check-runtime): Set GOLIBS to $(RT_LIBS). * configure, Makefile.in: Regenerate.
