Tidy jbig2dec build configuration:
1) Remove automake version specific tests/use
The script does unpleasant things which can cause us to attempt to use a
specific version of automake, which should not really be needed these days.
So we now just check that the automake version is greater than or equal to the
version we require.
The old method can still be accessed by invoking autogen.sh thus:
USE_OLD=yes ./autogen.sh
2) Add automake option to make dist "self contained"
The automake default is to symlink to a few scripts ('compile', 'missing' etc)
in the current system's automake install. That results in a configuration
reliant on automake being installed, and the same version, for a build.
Add the '--copy' automake option so the script files are copied rather than
linked, so we get a self contained configure/make/install setup.
No cluster differences.
