when i think about it some more, your latest statements are irrelevant. the
problem here is that if the __ASSUME_xxx defines are not defined, then glibc
falls back to the runtime test. as i illustrated in the original summary, this
will create a broken glibc if the linux-headers do not contain the pipe2 syscall
number. the arch in question is irrelevant. that means that the linux-headers
have to be very recent (and in some cases, not even available today let alone at
the time of the glibc-2.9 release).
