[OSy] CLion project setup, running, debugging

> Debugging setup:
The setup mentioned above works if the endianity is recognized by the mipsel-gdb and/or correctly set. If that doesn't work, one can make
a script wrapper around the mipsel-gdb, providing the gdb binary with arguments:

<path-to-mipsel-gdb>  -ex "set endian little" $@
make it executable and give it to CLion as "the" gdb.


Also there may be a problem with connecting to msim instances; currently can't tell better solution than relaunching the debugger.
