[OE-core] [PATCH v3] waf.bbclass: explicitly pass bindir and libdir if supported

[Stefan Agner]

From: Stefan Agner <stefan.agner at toradex.com>

On some build hosts distros (e.g. Fedora 26) waf tries to be
smart about libdir detection and defaults to [EXEC_PREFIX/lib64].
This obviously is not what we want for 32-bit targets and usually
fails in the do_package phase:
  WARNING: gstreamer1.0-plugins-imx-0.13.0-r0 do_package: QA Issue: gstreamer1.0-plugins-imx: Files/directories were installed but not shipped in any package:
    /usr/lib64/libgstimxcommon.so.0
    ...

Depending on version, waf knows prefix or prefix, bindir and
libdir as default options. Explicitly pass the right set of
arguments.
