[Bug target/93694] Inconsistent grammar in darwin.opt

--- Comment #1 from Roland Illig <roland.illig at gmx dot de> ---
double space:
> architecture  \"name\"


unnecessarily verbose:
> Specify that the output file should be generated for architecture  "name"

Why not simply: Generate output file for the named architecture.


anachronism:
> MacOS X

Should that be macOS nowadays?


off-by-one:
> must record a greater

I think this should rather be "greater or equal".
