Most arm target configs now require a 64-bit HW-int. Unfortunately a
few of the older, less commonly used config targets do not. The code in
arm.c now pretty much requires that a 64-bit HW-int is used, especially
for vectorization to work.
This patch makes 64-bit HW-int the default for all arm configs and
cleans up the configure script accordingly.
* config.gcc (arm): Require 64-bit host-wide-int for all ARM
target configs.
