Ian Lance Taylor 6d8af00a63 cmd/go,cmd/cgo: in _cgo_flags use one line per flag
The flags that we recorded in _cgo_flags did not use any quoting,
so a flag containing embedded spaces was mishandled.
Change the _cgo_flags format to put each flag on a separate line.
That is a simple format that does not require any quoting.

As far as I can tell only cmd/go uses _cgo_flags, and it is only
used for gccgo. If this patch doesn't cause any trouble, then
in the next release we can change to only using _cgo_flags for gccgo.

Thanks to Juho Nurminen of Mattermost for reporting this issue.

Fixes #60306
Fixes CVE-2023-29405
