[PATCH] D33873: [llvm-readobj] Accept (and ignore) --wide (-W) command-line switch

[Roland McGrath via Phabricator via llvm-commits]

mcgrathr created this revision.

Accept and ignore --wide/-W.  In GNU readelf this switch is                 
necessary to get the output format that's consistent between                
32-bit and 64-bit targets.  llvm-readobj always produces that               
output format.
