The signal numbers for these two signals come from HP-UX but the signals
are used
by Linux, so I can't see how they can change.

This signal isn't used by HP-UX but it is used by Linux, so again this
can't change.
Can we change _NSIG to 69 so there are 32 RT signals as on other arches?

Doesn't really matter...
