Merge from gnulib, using build-aux to remove clutter (Bug#9169).
This is to fix the following problems:
. On FreeBSD 6.4, HP-UX 11.31, and Solaris 9, and when Emacs is
configured not to use gtk or any other thread-using library,
signals aren't blocked correctly.
. On IRIX 6.5 it fixes an unwanted clash between Emacs's
and IRIX's signal handling.
. On Cygwin 1.7.5 it works around an incompatibility with
the system pthread_sigmask.
. On MacOS X 10.5 (32-bit), files whose inode numbers
exceed 2**31 cannot be read or manipulated.
. pthread_sigmask: Actually use results of gl_THREADLIB.
. strtoimax, strtoumax: Avoid link error on OSF/1 with DTK cc.
. find 'ar' program that fits with --host argument.
. Allow the user to override the choice of AR, ARFLAGS, RANLIB.

* fileio.c: Fix bugs with large file offsets (Bug#9428).
The previous code assumed that file offsets (off_t values) fit in
EMACS_INT variables, which is not true on typical 32-bit hosts.
The code messed up by falsely reporting buffer overflow in cases
such as (insert-file-contents "big" nil 1 2) into an empty buffer
when "big" contains more than 2**29 bytes, even though this
inserts just one byte and does not overflow the buffer.
(Finsert_file_contents): Store file offsets as off_t
values, not as EMACS_INT values. Check for overflow when
converting between EMACS_INT and off_t. When checking for
buffer overflow or for overlap, take the offsets into account.
Don't use EMACS_INT for small values where int suffices.
When checking for overlap, fix a typo: ZV was used where
ZV_BYTE was intended.
(Fwrite_region): Don't assume off_t fits into 'long'.
* buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
