It works for me; we routinely build gdb (including gdbserver) for a
mips target on an i386 host.  The switches are --host=<mipstarget>
--target=<mipstarget> --build=<i386host>.  And of course you need a
toolchain (compiler etc) for the target.

I may have had to pass CC=<targetcompilername> as well, I'm not sure
if that's needed.
