[PATCH 2/2] [ADA] Fix constants in s-linux-mips.ads

[Arnaud Charlet]

> This patch corrects various constants in s-linux-mips.ads. A large
> proportion (especially the signals) were simply wrong on MIPS. It also
> fixes the struct sigaction offsets which are incorrect on 64-bit
> systems because sa_flags is an int (always 32-bits), and not a pointer.

Change is OK.
