Enable multilib baremetal toolchains

Distro Changes:

  When building a multilib, we need to disable configsite cache.  Otherwise
  the system will fail to generate the SDK as there are no configsite entries
  due to newlib based multilibs.

Recipe Changes:

  gcc - globally disable multilib configuration
      - Disable Linux specific configurations (EXTRACONFFUNCS)
  gcc-cross-canadian - enable multilib on a recipe specific basis
  libgcc - add a noop override to do_multilib_install to avoid Linux specific
           multilib processing
  newlib - arm/v6+m/nofp and arm/v8-m.base/nofp do not have newlib trap
           implementations.  libgloss contains these, workaround by
           disabling builtin trap syscall handler.
         - misc workarounds for multilib installs
  libgloss - Allow MLPREFIX for newlib dependencies
  meta-toolchain - adjust to install only the items we want/need
  packagegroup-newlib-standalone-sdk-target - new pkggroup for the
           custom baremetal SDK to select the right set of packages
