You can probably look around and find the official gdb-4.17 release.

A better bet is to get from the mvista CDK 1.2 release:

ftp://ftp.mvista.com/pub/CDKit/1.2/cd/Source/SRPMS/hhl-gdb-5.0-1.src.rpm

It says gdb 5.0, but I think gdb-4.17 is "embedded" in it.  (If not, let me
know).

If you try to add linux-mips to gdb 5.0, you might want to look into the new
multi-arch structure introduced in gdb 5.0.  It *might* be the reason why
original MIPS stuff is removed.

Good luck.
