These are the first lines of every source file:
/*
 * This code was created by Jeff Molofee '99
 * (ported to Linux by Ti Leggett '01)
 * (ported to i.mx51, i.mx31 and x11 by Freescale '10)
 * If you've found this code useful, please let him know.
 *
 * Visit Jeff at http://nehe.gamedev.net/
 *
 */

I know the description is not the best one can produce, but this is not an 
established project, nor a one man/enterprise work. At least the X11 part is 
not Vivante's nor Freescale's specific at all.

I'll have multiple "workdirs", as this initial version is just for GLES1.1, 
but Samples folder has three subfolders:
GLES1.1
GLES2.0
OpenVG
each one has its own Makefile, and no common Makefile. I'm not interested in 
creating a common Makefile with a patch, as they might even get packaged 
separately in the future according to chipset support.
According to that, would you still use just:
WORKDIR = "${S}/Samples/GLES1.1"

Shorter code is not necessarily better or clearer code. However if you want 
I'll follow your suggestion.

This is related to the multiple subfolders (GLES1.1, GLES2.0, OpenVG) which 
will come later, so let's discuss the "WORKDIR" issue.

As above.

This is not in any way an "established project which installs in standard 
paths". It's more a "bunch of samples patched in the years, started quite some 
time ago, and intended just to be compiled and started locally by the learning 
developer".

Thanks for your review. If you can clear out the WORKDIR vs multiple Makefiles 
in subdirs issue I'll post the updated patch.

Bests,
