Add support for building static executables

This fixes the following issues:
* linked objects do not use LDFLAGS
* pkg-config is not queried appropriately depending on the desired linkage
* there's no way to configure/deconfigure static linking
  (except by setting LDFLAGS, which won't work due to the prior two)

There are many ways of fixing these, but I went for the minimally intrusive approach:
* any linked objects have `$(LDFLAGS)` in front of `$(LIBS)`
* configure has a --static and --dynamic flag
* --static is added to ldflags only if selected
