Allow using ash as the shell for ./configure and make.
After an idea by "Martin Guy" <martinwguy@yahoo.it>:

       Use gcc's option -pipe to use pipes rather than temp files when building
       the toolchain.

+      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.
