You are using a broken or incorrectly configured (for the purpose)
tool chain then.  I don't see such problems with ELDK.

All these boards build fine for me.

As it's mostly unmaintained and/or Freescale boards that are untested
because of your tool chain issues I guess we can assume the test
passed.

Thanks.
