Found that people who do not have the envirornment variable NITROS9DIR set before building the project get a error missing file "/rules.mak". Found this is caused do to the fact that the code to set this envirornment variable is in the rules.mak which can't get loaded. To fix this the code needed to set the envirornment variable that is in the rules.mak is now in the makefile(s) right before the include for the rules.mak file. This should fix the problem for those who do not have the NITROS9DIR envirornment variable preset.
