[Bug 2002251] [NEW] libtool 2.4.7 needs to be backported to Jammy

[Kamila Szewczyk]

Public bug reported:

Hello.

I am a maintainer of the bzip3 statistical data compression program.

My software is currently being packaged for Homebrew, however, the
reviewers found an issue caused by an outdated version of libtool in the
Ubuntu Jammy which is fixed in new libtool versions (e.g. 2.4.7-5 on
Debian Sid which I am using). The following patch to the `configure'
file as generated using `libtool.m4' needs to be applied, since the
logic in `libtool.m4' in this particular version is invalid:

Furthermore, we are compelled to use Ubuntu Jammy (I would have upgraded
otherwise), but Github Actions hosted runners do not support it, so us
and other maintainers who don't keep generated `configure' files in the
source code trunk would be very thankful for this backport.
