Move interpreter shared library detection to configure
For building PL/Perl, PL/Python, and PL/Tcl, we need a shared library of
libperl, libpython, and libtcl, respectively. Previously, this was
checked in the makefiles, skipping the PL build with a warning if no
shared library was available. Now this is checked in configure, with an
error if no shared library is available.
The previous situation arose because in the olden days, the configure
options --with-perl, --with-python, and --with-tcl controlled whether
frontend interfaces for those languages would be built. The procedural
languages were added later, and shared libraries were often not
available in the beginning. So it was decided skip the builds of the
procedural languages in those cases. The frontend interfaces have since
been removed from the tree, and shared libraries are now available most
of the time, so that setup makes much less sense now.
Also, the new setup allows contrib modules and pgxs users to rely on the
respective PLs being available based on configure flags.
