Uses x86-specific assembler code for trapping

As can be seen there: https://github.com/colobot/colobot/blob/dev/src/CBot/CBot.h#L39 , Colobot uses x86-specific assembler, which makes it unbuildable on other architectures.

See the build status and logs on other architectures: https://buildd.debian.org/status/package.php?p=colobot
