I don't like the idea of adding syscalls first and then disabling them
again. We tried that on score and now we're stuck with the wrong syscall
table there because they never got removed.

Instead, I'd suggest you do the minimal syscall table for upstream and
just carry a private patch to enable the other syscalls until you get
a working glibc/eglibc/uclibc with the official kernel.
