Deleted binary and compiled makefile from version control
Fixed warning chcon: failed to get security context

This came from the src/Makefile where opp_makemake generated some
SELinux context modification command at the end of the built.
Uncommenting did the trick but we may need to reconsider this in the
future if we have problems with the shared library and SELinux
make clean does now also make clean in th src/Makefile
