there should be no problems with gcc-3.4.6 and any architecture on the uClibc 
side  of things.  there is someone on who has spent a lot of 
time getting nios2 things working in uClibc again.

ah elf2flt, how i stab thee ... this will require custom modifications to your 
binutils install step

i'm pretty sure svn trunk of uClibc actually has a decent nios2 status.  it'd 
prob be faster to go the other way -- enable everything you expect and only 
turn off upon failure.
