Fix use of "command line X" in binutils doc

Binutils documentation uses a mix of spelling for the compound word
"command-line X". According to [1]:

"Sometimes compound words are written separately (nail polish),
sometimes with a hyphen (short-sighted) and sometimes as one word
(eyelashes). Often new compounds are written as two separate words and,
as they become more familiar, they are either connected with a hyphen
(-) or made into one word."

I think command-line X is common enough in our industry that the two
workds command and line should be connected. Since command-line is more
common than commandline, I propose to update binutils documentation to
consistently use "command-line" when this is used as an adjective to a
noun (eg. command-line argument, command-line switch, command-line
option and command-line flag). I've left occurences of "the command
line" as is. I've also left gdb, sim and readline alone and have only
touched public documentation (texi and NEWS files).
