Fix Sim for newer distros

__builtin found fix for rbendian.h
tools/configure defines SIM_USE_BYTESWAP_H if byteswap.h is found in
/usr/include/ maybe there is a better mechanism for this

genshortcut.sh is a simple script to make .desktop shortcut files
several newer distros don't allow you to run the simulator from the
file manager, this or perhaps a different method can probably be
included while building a sim at a later date.

for now it can be run manually like so:
similar to ../tools/configure
run from your simulator folder
../tools/genshortcut.sh exepath shortname icon
ex. ../tools/genshortcut.sh ./rockboxui clip+sim music-app
