Ok, so ld-linux.so.2 is doing the right thing (looks like
there must be a bug lurking in the uClibc ldd implementation).

bummer.  Was worth a try.  

Sorry about that, yeah I did the large file stuff a bit ago.
I'll go fixup the DOLFS comments.  Ok, fixed.

I was just looking back over the straces you gave me, and noticed
that in both cases, it was choking on a TCGETS ioctl.  That got
me looking at isatty() and tcgetattr().  Out of curiosity, what
kernel version are you using, and what does struct termio in
uClibc/include/asm/termios.h look like?
