signal.7: Reorder the architectures in the signal number lists 

x86 and ARM are the most common architectures, but currently
are in the second subfield in the signal number lists.
Instead, swap that info with subfield 1, so the most
common architectures are first in the list.

Several signal numbers

Where four values are given, the first one is usually valid for
alpha and sparc,
the second one for x86, arm, and most other architectures,
the third one for mips and the last one for parisc.
