I think you need to fix this problem rather than trying more and more
complicated workarounds. Essentially, the spec in OPTION_DEFAULT_SPECS
can't simply be "%{!msynci:%{!mno-synci:-m%(VALUE)}}" - it needs to be
something more complicated that avoids passing -msynci when it won't be
supported, or else it needs to pass an internal -msynci-if-supported
option which acts like -msynci except for not causing a warning.
