Problems with MIPS soft floating point support for gcc-3.2...

["Steven J. Hill" <sjhill at realitydiluted dot com>]

Greetings.

I've been beating my head on this, and I'm out of my
expertise at this point. I'm building a uClibc based
system, but whether I'm using glibc or uClibc is IMHO
irrevelant.

Attached is a patch that I have put together based upon
my searching the Internet and studying other people's
patches. It builds the separate GCC libraries just fine,
but when I go to link the final static uClibc C library,
it dies and prints a ton of multiple definition messages.
Can anyone give me some insight on what I am missing?
Thank you VERY much in advance.
