Vadim Zeitlin f10bd1279d Remove the correct directory from PATH for MinGW AppVeyor builds
We need to remove the directory containing sh.exe from the PATH as
otherwise mingw32-make seems to use it and not cmd.exe for executing the
commands in the makefile, but the wrong directory was being removed in
appveyor.yml, having no effect.

Fix this and undo 5f2ccde269 which
compensated for it by (almost) clearing the PATH entirely which, in
turn, broke one of our unit tests (and could break other things in the
future, as having an empty PATH is rather unexpected).

Also use the full path for head program now that its directory is not in
the PATH any more. Alternative could be to use PowerShell, but while

powershell -Command "'gcc','mingw32-make','ar'|%%{ iex \"$_ --version\"|select -first 1 }"

does work, it looks really ugly, so avoid it for now.

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.
