autoconf: upgrade to 2.71

After too many years, autoconf has made a new release.  On the whole it
is compatible with previous releases, but some macros are more specific
about what they expose so minor tweaks to configure.ac may be required.

autoconf also now invokes intltoolize, gtkdocize, and copies
config.sub/guess, so there is less work for autotools.bbclass to do.

- AC_HEADER_MAJOR-port-to-glibc-2.25.patch
- add_musl_config.patch
- autoconf-replace-w-option-in-shebangs-with-modern-use-warnings.patch
- autoreconf-gnuconfigize.patch
- check-automake-cross-warning.patch
- config_site.patch
- fix_path_xtra.patch
- performance.patch
Drop a number of patches which have been integrated upstream.

- man-host-perl.patch
Don't use the target perl path when building documentation at build time:

- no-man.patch
Don't build documentation in native builds to avoid further build
dependencies.

-Subject: [PATCH] AC_HEADER_MAJOR: port to glibc 2.25
-
-glibc 2.25 is deprecating the namespace pollution of <sys/types.h>
-injecting major(), minor(), and makedev() into the compilation
-environment, with a warning that insists that users include
-<sys/sysmacros.h> instead.  However, because the expansion of
-AC_HEADER_MAJOR didn't bother checking sys/sysmacros.h until
-after probing whether sys/types.h pollutes the namespace, it was
-not defining MAJOR_IN_SYSMACROS, with the result that code
-compiled with -Werror chokes on the deprecation warnings because
-it was not including sysmacros.h.
-
-In addition to fixing autoconf (which only benefits projects
-that rebuild configure after this fix is released), we can also
-give a hint to distros on how they can populate config.site with
-a cache variable to force pre-existing configure scripts without
-the updated macro to behave sanely in the presence of glibc 2.25
-(the documentation is especially useful since that cache variable
-is no longer present in autoconf after this patch).
-
-Note that mingw lacks major/minor/makedev in any of its standard
-headers; for that platform, the behavior of this macro is unchanged
-(code using the recommended include formula will get a compile error
-when trying to use major(), whether before or after this patch); but
-for now, it is assumed that programs actually concerned with
-creating devices are not worried about portability to mingw.  If
-desired, a later patch could tighten AC_HEADER_MAJOR to fail at
-configure time if the macros are unavailable in any of the three
-system headers, but that semantic change is not worth mixing into
-this patch.
-
-* lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Drop check for
-major within sys/types.h; it interferes with the need to check
-sysmacros.h first.

-Subject: [PATCH] perl: Replace -w option in shebangs with modern "use
- warnings"
-
-In some builds we might provide ac_cv_path_PERL as /usr/bin/env perl
-to use newer version of the perl from users PATH rather than
-older from standard system path.
-
-However using /usr/bin/env perl -w from shebang line isn't
-possible because it translates to something like
-/usr/bin/env -w perl and env complains about illegal option.
-
-To address this we can remove -w option from perl shebang
-line and add "use warnings" statement.

+Subject: [PATCH 2/7] m4sh: prefer bash over sh
 
-Some systems have /bin/sh -> dash and others /bin/sh -> bash. Bash is preferred 
-but sometimes we can sometimes end up exporting /bin/sh yet use bashisms.
+_AS_DETECT_BETTER_SHELL looks for a good shell to use, and tries to look for
+'sh' before 'bash'.  Whilst for many systems sh is a symlink to bash,
+there are many where sh is a symlink to a more minimal sh implementation.
 
-This patch puts bash first in the search results which avoids the bash/dash confusion.
+For example, Debian by default has /bin/sh -> /bin/dash: dash is a faster
+shell to start (which makes a notable difference to boot speed) but is not
+as fast as bash at executing long scripts (and configure scripts are not
+known for their conciseness).
 
-RP 2012/9/23
+Change the search order to bash then sh, so that a known-good shell (bash)
+is used if available over something which is merely POSIX compliant.

-We have problem using hardcoded directories like /usr/local here

-build host or target. Therefore we get rid of the hardcoded paths
