Is CPUTYPE=cortex-A7 supposed to work?

Thank you so much for your quick feedback Michal. Good to know this matter is into good hands. I’m afraid I'm still afraid about `basic’ programs like git being still potentially broken when kernel+world+ports have CPUTYPE=cortex-a7 in make.conf - Andrew said a simple `git clone' could fail, more precisely (quoting him):

Removing CPUTYPE apparently fixes things hence I’m not 100% confident yet of keeping CPUTYPE=cortex-a7 myself even if only a few ports might be affected. Git is an important port, who knows what other ports are broken :-) Are you also working on the kernel part (as part of the ‘other interfaces’ you mentioned) to fix this fp-register-preserving-during-signal? 

Thanks one more time for all analyses done so far and thanks in advance for future work on this matter :-)
