So back in 3.2 days I ran into these issues with elfutils - the workaround was to use the standalone libelf http://www.mr511.de/software/libelf-0.8.9.tar.gz. Not sure if you will be willing to take that path. OTOH, you could use standalone argp @ http://www.lysator.liu.se/~nisse/archive but it seems that requires a bunch of patches too - from looking into the corresponding buildroot package folder. Give this a shot - otherwise it is easier to just build a custom toolchain with pre-req packages from buildroot. Or can be provided if you so deem fit ! -Vineet
