The llvm-dsymutils from the llvm 3.7.1, llvm-3.8.1. llvm-3.9.1 and llvm-4.0svn
releases all fail to process the lto1. cc1, f951, cc1obj, cc1plus and
cc1objplus binaries from a FSF gcc 7.0svn build. The failures are slightly
different and using the attached FSF gcc 7.0svn build binaries with the llvm-
dsymutils from the Macports llvm-3.7, llvm-3.8, llvm-3.9 and llvm-4.0 packages
appears as....

Note that the llvm-dsymutils from Xcode 8.2.1 works fine but that that from the
Xcode 8.3 beta releases fails in yet a different manner on the FSF gcc
binaries...

cd /
sudo tar -jxvf sw.tar.bz2
cd /sw/src/fink.build/gcc7-7.0.1-1/darwin_objdir/gcc
sudo dsymutil lto1

with an 'Illegal instruction' error. The Xcode 8.3 regression is filed on radar
as 30613458 titled "dsymutil regression in Xcode 8.3 betas".
