config.bld' is not a valid build configuration file

```
What steps will reproduce the problem?
1. make TARGET_PRODUCT=omap3evm BUILD_WITH_GST=true dvsdk

/media/500_p1/Android/omap3evm/rowboat-android/eclair/external/ti-dsp/dvsdk_3_01

file. Stop.

What is the expected output? What do you see instead?
Searching for config.bld should be available in codec_engine_2_25_05_16 (file
is missing).

What version of the product are you using? On what operating system?

Start by reproducing `make TARGET_PRODUCT=omap3evm BUILD_WITH_GST=true dvsdk` on the stated Ubuntu environment and inspect the referenced xdc_rules.mak path. Check why codec_engine_2_25_05_16/config.bld is missing or rejected; done means the dvsdk build proceeds past the ce_build and config.bld errors.
