No strong opinion, we had everything inline so far.

No good reason "now".
I was first bitten by a reference to redhat-hardened-ld in some
libtool script in the tarball (/me looks in Dodji direction).
I then considered switching to different versions of libabigail by
just setting the LIBABIGAIL_VERSION env variable from .travis.yml.
I ended up with the current latest version which is also what is in
Ubuntu latest releases.
The tarball is smaller than a git clone, so best to use it.
v3 incoming.
