Ok, there are several serious problems with what you are trying to do...

Actually, it isn't identical, but that doesn't really matter...

Ok, stop right here.  Do you realize how little memory this device has? 
   You would be lucky to even be able to build some of the more simple 
programs without some sort of ICE or out of memory error.

You would really want -march=mips32 anyway.

That is not even close to the correct profile for uclibc.  You really 
want /usr/portage/profiles/uclibc/mips

You'll be extremely lucky if this ever works on that device...again, not 
enough memory.

This is probably telling that you have some serious issues...

  This is from selecting the wrong profile, aside from the fact that 
glibc even doesn't have a snowballs chance in hell of building on such a

That is an even worse idea.  The cobalt stages are optimized for 
-march=mips4, which probably won't run on that cpu.  Not only that, but 
they are glibc based, which is way too heavy to run on a wl500g

The moral of this story is, a broadcom based router is not good for 
using gentoo in the capacity you are trying to.  What you *really* want 
to do is emerge crossdev on a nice fast box, use that to build a 
crosstoolchain, and cross-compile a custom userland to run on your router.
