I am trying to use buildroot with an external toolchain.

The following output from buildroot seems to indicate that sysroot has
not been set up correctly:

checking for avr32-linux-gcc...
-Os -pipe -Os
--sysroot /home/neil/Projects/ICnova-20110104-2/ICnova/build_avr32/staging_dir/
checking for C compiler default output file name... configure: error: C
compiler cannot create executables
See `config.log' for more details.
make: ***
Error 77

The correct compiler has been invoked, but sysroot is not pointing to
the correct container for the compatible .../lib (which sits beside
the .../bin directory containing the compiler (actually a simlink to

Is my understanding correct? How can I fix this?
