Re: pkg/39377: python24 extensions fail to configure on Ubuntu Linux

If you build python against the db185 that's in NetBSD's libc (and the
libc of every 4.4-derived system) that -ldb4 won't be there:

   % grep -- '^LIBS=' /usr/pkg/lib/python2.4/config/Makefile
   LIBS=           -lpthread  -lutil

However, if on such a system you do build python against db4, and it's
not there, the linker will likely find the db185 functions in libc,
and that is extremely likely to make a mess. So it needs to be there
in at least some cases. (And depending on exactly what this is used to
link against, it might be needed on Linux too; one of the charming
properties of ELF shared libs is that failing to link with needed libs
when building one is nonfatal and silently results in an output file
with shared lib dependencies missing, which can cause assorted subtle
problems later on.)

In light of these things I think your following patch is the right
