Illegal instruction when running plmerge or a built app

[Alister Hood]

Hi, I'm trying to get started with Gnustep on Arch Linux (x86).
Whatever I try to build, there is an error like this:

/bin/sh: line 2: 23312 Illegal instruction plmerge 
GSTest.app/Resources/Info-gnustep.plist "GSTestInfo.plist"

And when I try to run the app that was built I just get an "illegal 
instruction".

I have tried with the official packages in Arch:
gnustep-back 0.20.1-1
gnustep-base 1.23.0-1
gnustep-gui 0.20.0-3
gnustep-make 2.6.1-1
I have also tried with self-built gnustep from svn, and got the same 
results.

Below is the output when I build the Calculator test with debugging enabled.
Does this indicate whether it is a problem with gnustep, or with some 
other dependency or something?

Thanks,
Alister
