Problems building cross compiler for MIPS on a Sun Sparc.

[Kristina.Lundqvist@docs.uu.se]

I am trying to build a cross gcc for an Algorithmics P-4032 single board
computer with a MIPS R4000 CPU. I'm attempting this on a Sun-Sparc-Solaris2
system.

The version of binutil is 2.8.1 and the version of gcc is also 2.8.1. I follow
the texinfo file on Using and Porting GNU CC and have done the following

1. Configured and built binutils (see history list items 11-17 below)

   - Binutils builds ok (so far as I know) and installs ok (also as far as I
     know). 

2. Configured gcc (see history list items 20-24 below)

   - However, with the configuration for GCC (item 21) the compilation
     of GCC ends with an error while building libgcc2.a. It seems that
     inappropriate flags have been passed to as. 


Have anybody encountered the same problem? What did you do to get around it?

Regards

  Kristina
