[Lazarus] Lazartus on RaspberryPi 64 bit - build for all RPi versions?

[Alexey Torgashin]

fpcUpDeluxe allows to install additional FPC folder. with 'crosses' - 
for ex, I have additional FPC on Linux with crosses for Windows, Linux 
ARM, *BSD x32+x64, macOS x64+ARM. In the IDE you can specify that new 
FPC installation. Using IDE 'build modes' you can make N new modes, one 
mode pear each CPU/OS case.
