Merge changes from GCC for the config/ directory

GCC's config/ChangeLog since the last time this merge was done
(in the binutils-gdb commit 0b4d000cc4e8e77c823) is included at the
end of this commit message.

It is worth noting that the binutils-gdb commit 301a9420d947da1458
added the file config/debuginfod.m4 which is not present in GCC's
config/ directory.  This file is preserved, unmodified, after this
commit.

In order to regenerate all of the configure files, I configured with
--enable-maintainer-mode, and built the 'all' target.  I then did the
same thing on a source tree without this patch, and only committed
those files that changed when this patch was added.

+# SYNOPSIS
+#
+#   AX_COUNT_CPUS([ACTION-IF-DETECTED],[ACTION-IF-NOT-DETECTED])
+#
+# DESCRIPTION
+#
+#   Attempt to count the number of logical processor cores (including
+#   virtual and HT cores) currently available to use on the machine and
+#   place detected value in CPU_COUNT variable.
+#
+#   On successful detection, ACTION-IF-DETECTED is executed if present. If
+#   the detection fails, then ACTION-IF-NOT-DETECTED is triggered. The
+#   default ACTION-IF-NOT-DETECTED is to set CPU_COUNT to 1.
