Dear Thomas Petazzoni,

Apparently, what changed is that the gcc/configure.ac has gained a
AC_SYS_LARGEFILE check:

$ grep LARGEFILE toolchain/gcc-4.6.3/gcc/configure.ac 
AC_SYS_LARGEFILE
$ grep LARGEFILE toolchain/gcc-4.5.4/gcc/configure.ac 
$

On gcc >= 4.6, this means that a #define _FILE_OFFSET_BITS 64 is added
to auto-host.h, which breaks the build of crtstuff.c for the target as
uClibc headers warn that _FILE_OFFSET_BITS is set to 64 even though
largefile support is not enabled.
