Pertaining to the Android User's Guide from Freescale, Document Number: AUG, Rev KK4.4.3_2.0.0-ga, 02/2015
While following instructions in section 3.4 Building Android images
$ cd ~/myandroid
$ source build/envsetup.sh
$ lunch sabresd_6dq-user
$ make 2>&1 | tee build_sabresd_6dq_android.log
I discovered an error after the first make command:
make: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp] Error 127
Some online searching revealed a nice list of common android errors and the suggested solutions:

In this case, the solution is to install the flex package (not mentioned in the document)
sudo apt-get install flex
