Waf conversion: Convert led/posix_*
completed by: Chirayu Desai
mentors: Chris Johns, Gedare
First complete one of the Getting Started tasks.
This task assists the effort of converting the build system for the RTEMS examples-v2.git repository of sample applications from using a set of custom Makefiles to using Waf. Follow the instructions given in the RTEMS GoogleCodeInProjects Wiki page for the directories: examples-v2/led/posix_* comprising posix_cond_server, posix_delay_nanosleep, posix_delay_sleep, and posix_mutex_server. Also fix the recurse() call for ratemon_cond_server to be conditional on whether or not POSIX is enabled. You will upload a patch file containing the modifications you make. Please also submit your work as a pull request on GitHub.
For this task you will need to test for whether or not POSIX is enabled before calling recurse() into the sub-directories.
