if set -o pipefail 2> /dev/null; then
The intention is to test for the existence of the pipefail option.
When the busybox version of ash is used as /bin/sh, this line causes the script to exit, instead of "set -o pipefile" returning nonzero exit status and letting "if" do its thing. The net result is that "ldd" silently exits, instead of doing its job of displaying library dependencies.
A patch to fix this is attached. The patch changes the behavior of the "set" command so that instead of bailing out if presented with an unrecognized argument to "-o", it returns exit status 1 (the same as bash).
The patch is against the version of ash in Busybox 1.1.0
