Yes, I know I'm definitely working with 2.4 sources.  2.5's menuconfig 
still confuses me somewhat due to it's more organized layout.

It's a cross compiler, specifically a sparc -> mips one, as my sparc 
machine is the fastest machine (Blade 100) running linux on my network 
atm.  I stuck to the .16 binutils initially because I didn't know how to 
address the -mcpu curiosity that appears in .18 and .20.  I originally 
thought that binutils was broken on mips, but after thinking about it, I 
partially suspect -mcpu has been gutted from the usable options.

I'm wondering if there are some strange oddities a slightly older 
binutils such as .16 may have in relation to the CVS kernels.  In all 
likely, it's probably something else I'm overseeing, but I'm trying to 
eliminate possible causes and get to the root of this problem.
