Will add ATTRIBUTE_UNUSED.
It requires documentation

It's more detail described in common-target.def:
'The hook is used for options that have a non-trivial list of\
possible option values. OPTION_CODE is option code of opt_code\
enum type. PREFIX is used for bash completion and allows an implementation\
to return more specific completion based on the prefix. All string values\
should be allocated from heap memory and consumers should release them.'
Should I copy it to the implementation.

ARM folks requested that, they want to do a smart filtering for bash completion.
It was there request.

Good point!
I wonder why misspellings are to be checked for the bash
> completion case?
Note that option_proposer::build_option_suggestions is shared infrastructure
in between bash completion and misspellings.
2 examples:
$ /xgcc -B. -march=znver2 -c /tmp/empty.c
cc1: error: bad value (‘znver2’) for ‘-march=’ switch
cc1: note: valid arguments to ‘-march=’ switch are: ... did you mean ‘znver1’?
$ ./xgcc -B. --completion=-march=znver
-march=znver1

What a question, I asked the same one before I implemented that. It's because
you have modifiers like: -march=armv8.3-a+simd+crypto+nofp for aarch64 target.
For i386, it's also manually parsed because of tables that group
options and various values:
processor_target_table
processor_alias_table
I'm sending updated version of patch that I'm going to test.

PREFIX is used for bash completion and allows an implementation to return more specific completion based on the prefix.
