[yocto] [meta-gplv2][PATCH] bc: use u-a for bc as well

[Martin Jansa]

* bc can be provided by busybox as well (e.g. if you have your own
  defconfig and forget to explicitly disable it:
  ...
  *
  * Miscellaneous Utilities
  *
  adjtimex (4.7 kb) (ADJTIMEX) [N/y/?] n
  bbconfig (9.7 kb) (BBCONFIG) [N/y/?] n
  bc (45 kb) (BC) [Y/n/?] (NEW) dc (36 kb) (DC) [Y/n/?] y
    Use bc code base for dc (larger, more features) (FEATURE_DC_BIG) [Y] (NEW) y
      Interactive mode (+4kb) (FEATURE_BC_INTERACTIVE) [Y/n/?] (NEW)     Enable bc/dc long options (FEATURE_BC_LONG_OPTIONS) [Y/n] (NEW) beep (2.4 kb) (BEEP) [N/y/?] n
  chat (6.3 kb) (CHAT) [N/y/?] n
  conspy (10 kb) (CONSPY) [N/y/?] n
  ...
  ), causing conflict in u-a:

  update-alternatives: Error: not linking /usr/bin/bc to /bin/busybox.nosuid since /usr/bin/bc exists and is not a link

  and then whole do_rootfs or do_populate_sdk to fail because busybox postinst is failing:

  do_populate_sdk: Postinstall scriptlets of ['busybox'] have failed. If the intention is to defer them to first boot,
  then please place them into pkg_postinst_ontarget_${PN} (). Deferring to first boot via 'exit 1' is no longer supported.
