On an arm-none-eabi cross this test takes about 8 minutes to run on my 
machine. This is about 25 times longer than the whole of the rest of the 
binutils+gas+gdb testsuites put together.

Tests run on a 2GHz amd64, ie. not a slow machine.

A native i386 linker completes the test in a more reasonable time (~20 
seconds), so this looks like an arm specific problem.

We should probably figure out what causing this slowness. Until that happens, 
the patch below disable the test on arm targets.
Ok?

I'll file a bug in bugzilla to remind me/us that there's something slow in the 
arm linker.
