Isn't that a problem for all architectures in ports since they don't 
have check-abi data? I would assume that for ARM you want to disable it 
since the check will always fail...

I'm fine with removing the configure option at all since I normally use 
x86-64 ;)

If we switch it on, we should ping all architecture maintainers to 
provide good data. AFAIK current glibc has good check-abi data on Linux 
for x86 and x86-64 but bad data for  s390, s390x, powerpc and powerpc64 
(that's what I tested).
