no that was accidentally removed in your suggested workaround for PR39491.

I'll ask the Debian ARM port maintainers. would welcome feedback from GCC ARM
maintainers as well.

baseline files would help. Debian itself does include symbol files as well, but
in this case I didn't update those when adding the new armeabi support. But I
only will notice such regressions when building the package for Debian or
Ubuntu, which I did for arm not before the 4.4 release.
