Prototype warning for clock_nanosleep()

[Gedare Bloom]

This is/should be based on the definition of _POSIX_CLOCK_SELECTION
and we get this from newlib/libc/include/sys/features.h as of commit
9a80679aae9098aa189f7ea8ce7892e2c092f3be in newlib.git. If there is a
warning, then probably rsb is not getting a new enough newlib for it.
