Subject: build error with iw-0.9.21

I'm getting a linker error when I compile the latest 'iw-0.9.21' package with 'libnl-2.0'.

Note: I'm cross compiling for an ARM platform using CodeSourcery tools.

Any help appreciated.

thanx

Well, looks like you should be linking against libm, but that wasn't
usually necessary to explicitly specify.
