That was a good tip. I Actually set CFLAGS and CXXFLAGS in the
environment before starting a new build:

$ getconf LFS_CFLAGS
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
$ export CFLAGS=`getconf LFS_CFLAGS`
$ export CXXFLAGS=$CLFAGS

That did the trick of getting largfile suppoort in uuu.

Alas, I've now run into harder obstacle:
mmap2(NULL, 3600000000, PROT_READ, MAP_SHARED, 3, 0) = -1 ENOMEM (Cannot 
allocate memory)

I'm pondering the possibility to rewrite uuulib to be able to flash
from file descriptor instead of memory buffer, but this does not seem
like a thing i'd like to spend my time on...

Maybe it is possible to splite devkit.img into smaller pieces and
write a bit diffrenet flashing script.

But for now I'm setting it aside, buying some bribe beer and
calling a friend. Chances are I might use his computer for flashing.
