gdb cross-debugging for MIPS linux target

[Jun Sun <jsun@mvista.com>]

Does anybody know if I can use gdb to cross-debug a MIPS/Linux target
with i386/Linux host?

I downloaded gdb source and tried "./configure --target=mipsel-linux" on
my i386/Linux host.  I got an error saying "mipsel-unknown-linux-gnu"
not supported.

If such a port does not exist, can someone point to me a starting place
where I can do the port myself?

Thanks.
