Use /bin/ash as the shell used by ./configure scripts.
./configure scripts make intensive use of calling a sub-shell, and the
traditional bash is slow, whereas ash is faster.
Saying 'y' here should be safe enough, but some components may not
accept using a shell other than bash (this is most probably true for
old versions). If you have trouble, say 'n' here and see if it fixes it.
