Vadim Zeitlin cc8657e436 Upgrade libjpeg to the latest version 9b
There don't seem to be any really important changes affecting our use of
the library, but it seems better to use the 2016 version instead of the
1998 one and it also allows to get rid of many hacks that were needed
before as the things they worked around are now taken care of by the
library itself.

autogen.mk

autogen.mk is a makefile provided to automatically update the GNU autotools
build system.  It will run Bakefile, aclocal, and autoconf as appropriate.

The .m4 files required for running aclocal are located in build/aclocal.
When upgrading software that wxWidgets depends on (for example, Bakefile,
cppunit, GTK, SDL, or others) it is advisable to upgrade the .m4 files
located in the build/aclocal directory.

It is particularly important that if you use a newer version of Bakefile
to generate the Makefile.in files that you use the newer bakefile*.m4.
Because build/autogen.mk is a Makefile it will automatically rerun
aclocal and autoconf as necessary whenever any m4 in build/aclocal is
newer than the generated aclocal.m4.

You can achieve this simply by copying the new bakefile*.m4 files from 
PREFIX/share/aclocal/ into the build/aclocal/ directory and
rerunning make -f build/autogen.mk.  Note that you should _not_ preserve
source file times (don't use cp -p) or else it's possible your .m4 files
will be older than the generated aclocal.m4).
Example:
cp /usr/share/aclocal/bakefile*.m4 build/aclocal/
make -f build/autogen.mk

Please don't forget to commit updated .m4 files as well as updated aclocal.m4,
configure, and Makefile.in files to wxWidgets.
