I'm sorry you've run into problems. Thank you for using the bug reporting
tools provided.
The problem lines in the output are (split to avoid grossly overlong lines
— but mail clients may do more damage to them):

(.text+0x20): undefined reference to `main'
Informix.o: In function `XS_DBD__Informix__dr_driver_init':
Informix.c:(.text+0x1e): undefined reference to `PL_thr_key'
followed by many, many more similar undefined references. The reference to
`main` is interesting; it tells me that things have gone horribly wrong,
but in a fairly tightly-constrained area of the code, namely the linking of
the shared library.
Further debugging information is going to be necessary; I recommend keeping
it off the DBI Users mailing list.
Please run the build phase (no need to redo the configuration phase; no
need to remove the object files) with these environment variables set:
DBD_INFORMIX_DEBUG_ESQLLD=1 \
DBD_INFORMIX_DEBUG_ESQLCC=1 \
make 2>&1 | tee dbdix.log
This should give information about what is going on inside the esqlld and
esqlcc scripts. Send the output file dbdix.log to [email protected],
please.
At this stage, my best guess is that the Makefile.PL has clobbered some
important flag so that the shared object build thinks it is trying to build
a program and not a shared library. However, this may well involve
tinkering inside Makefile.PL in the medium term, which is not a pleasant
thought — it is ugly code! And some of the 15 year old hacks may well have
outlived their usefulness, and the ways used to tweak ExtUtils::MakeMaker
settings may be ... sub-optimal, shall we say.
Do you still have the source for DBI around? If so, I may end up asking
you to build that and send (some of) the output from that, simply to
provide a comparison between 'working' (DBI) and 'not working'
(DBD::Informix) shared library build command lines.
