Summary:
llvm-{objcopy,strip} (and many other LLVM binary utilities) accept
cl::opt style -long-option as well as many short options (e.g. -p -S
-x). People who use them as replacement of GNU binutils often use the
grouped option syntax (POSIX Utility Conventions), e.g. -Sx => -S -x,
-Wd => -W -d, -sj.text => -s -j.text
There is ambiguity if a long option starts with the character used by a
short option. Drop the support for -long-option to resolve the ambiguity.
This divergence from other utilities is accepted (other utilities
continue supporting -long-option).
