scripts/bootstrap-prefix.sh: support sys-libs/glibc.

  - do not need a linker in stage2 on RAP.
  - binutils-config and ldconfig should be called explicitly
  - lto of gcc should be disabled. ld points to the host dynamic
    loader and gcc points to the RAP one, ld cannot load the gcc
    lto plugin.
