Strange ACATS fails in acats.log

[Richard Guenther]

I'm experiencing ACATS failures that manifest in

splitting 
/abuild/rguenther/obj4/gcc/testsuite/ada/acats/tests/a/ada101a.ada into:
   ada101a.adb
BUILD
FAIL:   ada101a
BUILD
FAIL:   c760009
splitting 
/abuild/rguenther/obj4/gcc/testsuite/ada/acats/tests/cd/cd2a22i.ada into:
   cd2a22i.adb
BUILD
FAIL:   cd2a22i

to appear in the logs, but nothing else.  What's this about?  Can we make
the log a little more verbose here please?

Thanks,
Richard.
