Makefile: Little Improvements
* not all platforms have gnu find
* not all platforms have rm
The user may adjust the settings in the header of the makefile
committer: Markus Bröker <mbroeker@largo.homelinux.org>
Profiling support added
* To use the benefits of profiling, set PROFILING=<target>
* eg: mbroeker@localhost $ make -e PROFILING=linux
* mbroeker@localhost $ export PROFILING=linux && make
