Rework the env - variables to produce a working cross compile script

The cross compile script kind of works right now, it's missing
something that I'm really not sure where or what it is.

currently sqlite will not build because:
	error: gethostuuid is not defined in iOS

This bug was already opened on sqlite bugtracker for about a year, the
workaround is to pass -DDSQLITE_ENABLE_LOCKING_STYLE=0 to the compilation
flags, which I did but did not work for some reason.

Which is a good error - it shows us that we are actually trying to compile
for iOS.
