gas uses ZSTD_compressStream2 which is only available with libzstd >= 1.4.0, leading to build errors when an older version is installed. This patch updates the check libzstd presence to check its version is >= 1.4.0. However, since gas seems to be the only component requiring such a recent version this may imply that we disable ZSTD support for all components although some would still benefit from an older version. I ran 'autoreconf -f' in all directories containing a configure.ac file, using vanilla autoconf-2.69 and automake-1.15.1. I noticed several errors from autoheader in readline, as well as warnings in intl, but they are unrelated to this patch. This should fix some of the buildbots. OK for trunk? Thanks, Christophe
