...as discussed at
<https://lists.freedesktop.org/archives/libreoffice/2018-November/081423.html>
"Re: Compiler baselines".

It doesn't look exactly right to enable the Developer Toolset from autogen.sh.
But the alternative would be to "hide" that in
<https://ci.libreoffice.org/job/gerrit_linux_gcc_release/configure>, which would
probably not be helpful when developers try to track down why a certain Jenkins
build behaves the way it does.  So pragmatically stick it in autogen.sh.  (Also,
it puts Developer Toolset on the PATH whenever it is found on a system using
LODE_HOME, not just for the specific Config=linux_gcc_release_64 case.  Lets see
how that works out in practice.)

However, it turns out that the Developer Toolset 7's GCC 7.3.1 with
--enable-werror (that is implicitly enabled for LODE-driven builds in
configure.ac) and (implicit) --enable-optimized produces many false warnings
(i.e., errors), see below for a sample.  (Actually, my experience is that
contemporary GCC hardly ever work with -Werror in optimized builds, due to
analysis being done on already optimized code; it surprised me to find out that
the Jnekins linux_gcc_release_64 builds were apparently successfully done with
--enable-werror with GCC 4.8.5.)  So explicitly --disable-werror for these
builds.  (Which means that <https://gerrit.libreoffice.org/plugins/gitiles/lode/
+/b82e0a9d26ef4c81046c053ff831dccfc84c56be%5E!> "For linux_gcc_release_64, don't
let ccache strip comments" could probably be reverted again if it has negative
impact on Jenkins' performance.)
