[patch, ARM] require 64-bit hw-int for all arm targets
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.

The configuration in libcpp/configure.ac of which targets need 64-bit HOST_WIDE_INT always needs to be kept in sync with that in gcc/config.gcc. -- Joseph S. Myers jos...@codesourcery.com
