This is a series completing the fix for PR55522 which got a fix for x86-linux already but left all other targets unfixed (including x86-cygwin, x86-darwin and x86-mingw32). The following series applies a similar change to other specs using crtfastmath.o, the changes are untested.
Target maintainers are CCed and I hope they can smoke-test the changes. x86 maintainers, can you please adjust the missed specs yourself? Thanks, Richard.
