I've run into this as well. It looks somewhat related to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=314435
As the maintainers explained there, nanosleep isn't part of the c99 standard (it is part of the posix standard). When you set -std=c99, that turns off -D_GNU_SOURCE, which turns off _POSIX_C_SOURCE in features.h, which turns off nanosleep, amongst other things. Not clear on exactly why this didn't matter in go 1.9, however.
