It turns out to be painful to require linking against -lrt on GNU/Linux, as that makes it harder to link Go code into C programs. Instead just call the timer syscalls directly. That is what the upstream library does anyhow. gcc/go/ * gospec.cc: Revert 2022-02-09 change: (RTLIB, RT_LIBRARY): Don't define. (lang_specific_driver): Don't add -lrt if linking statically on GNU/Linux. gotools/ * configure.ac: Revert 2022-02-09 change: (RT_LIBS): Don't define. * Makefile.am (check-runtime): Don't set GOLIBS to $(RT_LIBS). * configure, Makefile.in: Regenerate.
