After updating to 2010.2, the updated versions of a several packages
won't build. For example, busybox-1.16 fails like this:
make[1]: Leaving directory `/home/nextgen/buildroot/buildroot/output/build/busybox-1.16.0'

I believe the failure is due to the fact that no --sysroot option is
being specified in the link command. There _is_ a coorect --sysroot
option during compilation (see the EXTRA_CFLAGS value at the beginning
of the log), so I know that SYSROOT_DIR is set correctly.
After updating, I see other related failures building other packages
(mtdutils fails during compilation because include files can't be
found). Older versions of these packages always built fine.
It looks like the passing of --sysroot to external toolchains no
longer works...

The patch below seems to fix the problem. I don't really understand
why it worked before. That was with gcc 4.3 instead of gcc 4.4, so it
could be that 4.4 is pickier about locating library files.
I'll file a bug report and submit the patch.
