Comment (by kgardas):

 Shouldn't we rather fix gmp's configure which obviously misdetect shell
 instead of this workaround? As I said, your patch although it fixes the
 issue is incorrect IMHO.
 Or even better shouldn't we analyse why gmp's configure misdetects the
 shell and set wrong SHELL variable? This will be IMHO more correct/clear
 solution...
