Not really: configure script usually tests for a library by calling
the pkg-config command, and even if it tries to build a test program
with the library, that test program definitely cannot call all of the
functions that Emacs does, and thus cannot find such problems with
100% probability.

I'd suggest to report this to the Ubuntu package maintainers: it
sounds like their packaging has some problem.
