You didn't say if removing the lines in crt.S and Makefile fix your
issue.
Does it?

Now in that misoc/README you referenced, it mentioned installing
gcc...I am attempting to do so but I don't find a gcc-core and gcc-g++
but just one large (105MB) gcc file. I tried running configure and it
complained about needing these before proceeding, do they need any
special target options or just plain vanilla compile..
configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC
0.8.0+.

Okay, got a new binutils installed and the

recompile the entire gcc for lm32...its still using the

Your binutils does not support lm32 MMU, you should at least use
binutils 2.23.2
OR you can use binutils from my github repository:
https://github.com/fallen/lm32-binutils-mmu [1] but I would strongly
recommend using upstream binutils 2.23.2 or superior.
OR if you don't want to use the MMU anyway, you can just remove the
MMU unit test from the list by removing the lines 53 84 85 86 in
https://github.com/m-labs/lm32/blob/master/test/unittests/Makefile
[2]
That would be the fastest and cleanest solution for you if you don't
care about unit testing the MMU :)
I forgot to say to remove everything from line 86 in this file:
https://github.com/m-labs/lm32/blob/master/test/unittests/crt.S#L86

Do those issues manifest themselves with a fresh binutils, or the
outdated Lattice binaries?
