So, R links with rt if this configure check succeeds: AC_CHECK_LIB(rt, clock_gettime) Sure enough, on aarch64 and ppc64le, there is no clock_gettime in librt.so.1. I'm not sure _why_, but there is probably a good reason. I now understand why these builds are failing and have several paths to workaround it.
