* Remove symlinking of files located outside api_examples/
* Auto generate dependencies for files located outside api_examples/
* Update names of variables to be similar to those in tools/Makefile
* Fix out of tree build error Dependencies are calculated for all files in the SRCS variable. Previously, the SRCS variable contained files which were symlinked into the api_examples/ directory. These symlinked files did not exist when dependencies were calculated when building out of tree. This resulted in errors such as: make[1]: *** No rule to make target `/work/wd/tmp-ppc/api_examples/.depend', needed by `_depend'. Stop. make[1]: Leaving directory `/home/wd/git/u-boot/work/api_examples' make: *** [depend] Error 2
Since symlinked source files are no longer used, this bug no longer exists.
