make --enable-split-debug the default for debug builds, if available
Currently done only on Linux, as I'm unsure about the status on other platforms, and it seems that on Darwin the test passes successfully but later there are problems. Feel free to add your platform. https://lists.freedesktop.org/archives/libreoffice/2018-June/080437.html https://lists.freedesktop.org/archives/libreoffice/2018-July/080484.html Change-Id: I232ead45a1aff15cc738c612750ac28aedc08e83 Reviewed-on: https://gerrit.libreoffice.org/65425 Tested-by: Jenkins Reviewed-by: Luboš Luňák <l.lunak@collabora.com>
