Could you please provide some guidance on what needs to be done for Hurd?

Neither Andrew, nor I, know anything about Hurd signals.

Would it be ok to put a "stub" _dl_mask_all_signals() into
sysdeps/mach/hurd/dl-sysdep.c, and provide real implementation in
sysdeps/unix/sysv/linux/dl-sysdep.c ?

I've corrected this, and all other formatting deficiencies of Andrew's
patch (all that I could find, that is), and will resend it as soon as
I understand what to do about Hurd.
