Spack ABI check doesn't work properly with Apple gcc 4.2.1 (which is clang) #3529
Description
libdwarf failure when building it with elfutils for elf. I tried to install 'libdwarf@20130207%[email protected]'
and encountered an issue. I believe this is because of the recent changes @lee218llnl did with elf. Stack trace is below and gave multiple examples of how to cause the issue.
./bin/spack install libdwarf@20130207%[email protected]

@lee218llnl Should we set the default elf implementation back to libelf
