[Buildroot] [PATCH 2/3] core: waf-package infra: add missing additional variables for each build step

[Romain Naour <romain.naour@gmail.com>]

Some waf packages may want to pass additional variables to waf script
in each build step. Add the possibility to do so by defining the
following variables:
  <pkg>_MAKE_OPTS for the build step
  <pkg>_INSTALL_STAGING_OPTS for the install to staging directory
  <pkg>_INSTALL_TARGET_OPTS for the install to target directory
