IIUC  NOT_IN_libc is defined by libraries that we build along with
libc which have access to libc sources when they are built but are not
libc (e.g. librt )
and _LIBC is defined for libc code. Unless we want to bar these
associated libraries from including bits/uClibc_errno.h the current
check should be ok.
