Turns out that both Debian and Ubuntu might have different versions of
llvm and clang installed. You need to use llvm-config to figure out
where the development files can be found. I sent a patch for that.

Unfortunately then on the debian i386 old-stable install gcc turns out
to be not new enough. The plugin interface is missing for_each_plugin

annobin.cc: In function ‘bool multiple_annobin_plugins_present(const char*)’:
annobin.cc:3317:3: error: ‘for_each_plugin’ was not declared in this scope
 3317 |   for_each_plugin (callback, & cbd);
      |   ^~~~~~~~~~~~~~~

You can configure and build with --without-gcc_plugin but there are
very few tests that are able to run (I did sent a patch to
disable/SKIP a few more).

There were also a couple of tests that contained a wrong check to see
whether zip, unzip, tar and xz were installed. I sent another patch
for that. But even then there are several make check failures on
Debian or Ubuntu based systems (which I haven't investigated yet).

Cheers,

Mark
