[PATCH PR d/92792]: Committed reset libtool_VERSION to 1:0:0

[Iain Buclaw]

Hi,

This patch resets the libphobos soversion.  Firstly, because Phobos,
being template heavy, makes no attempt at being backwards compatible
with previous versions.  Even improvements in attribute inference in the
compiler can have the effect of changing the mangling of many symbols,
which is what I think happened in the case of the PR.  Secondly, the
current versioning scheme corresponds to the upstream release version of
Phobos, which in hindsight was a mistake to have done.

Cc Matthias who has been running with this patch in Debian for a while
now.

https://sources.debian.org/src/gcc-10/10-20200312-2/debian/patches/libphobos-soversion.diff/

Bootstrapped and tested on x86_64-linux-gnu, and committed to trunk.

Regards
Iain.
