makefile patch for compiling 32bit binaries on 64bit linux

[paco_m]

My first (very small) contribution here
As we encountered a severe bug in the 64bit version (reported on german forum) that according to Dwachs won't be fixed very soon,
I had to compile the posix simutrans in 32bit for my game server.
It took me quite a long time to figure out how to achieve this, at the end it is just adding -m32 to the gcc options and passing this options to the ld linker; my patch is adding a "linux32" ostype to the makefile and activates the before missing pass of gcc options to the linker.

Out of interest - what's the 64-bit bug? I know that in Experimental, running the 32-bit binary on Linux 64-bit results in bizarre behaviour on occasions; I don't know whether the same problems will occur in Standard. One alternative is to run the Windows version under Wine...

I see. Has anyone experienced the like issue on the 64-bit version of Simutrans-Experimental?

It was reported also on Mac OS X by cruzer, however I have some new information on this issue and decided to report it here

Aparently the connected bug report was closed. SO I am also closing this.
