Nevermind. I think I understood the problem. This tweaking of TUNE_CCARGS is resulting in premature evaluation in case of multilib and we are ending up with 64bit options when using 32bit gcc
Now, I have fixed this by patching glibc itself. see

http://git.openembedded.org/openembedded-core-contrib/tree/meta/recipes-core/glibc/glibc/0001-When-disabling-SSE-also-make-sure-that-fpmath-is-not.patch?h=kraj/gcc-glibc-upgrade

as a result all CCARGS patches aren’t needed any longer.

This should be good with multilib now. Please try the latest patchset.

Thinking of TUNE_CCARGS pruning, I think mips multilib will have similar issues, probably that flag should also move into glibc build system but I will leave that for another day
