I regenerated the ABI files, but it seems generated  libc abilist is lacking 
malloc_{get,set}_stated and had to be added manually - which causes a subsequent 
testsuite failure. Is this (manual addition of entries to abi file) correct or is 
this a deficiency of ARC port.

Speaking of testsuite, since this is bootstrapping a glibc system we have to 
resort to using scripts/cross-test-ssh.sh which is a serious pain in the neck. Is 
there no easy way to build the whole test suite first and then just run it on target.
