The problem with evaluating $(prefix) in configure phase is that autoconf does a lot of magic with this variable. Firstly, if the --prefix argument is not set for the configure script, the variable will have value "NONE". Wait, wat? Secondly, even autoconf scripts then have special cases for when variable is "NONE". It's even worse - whenever they need to construct new path based on prefix, they save its current value, substitute it with proper value (like /usr/local/), do what they need and then restore the original value. Le sigh. This mad behaviour is, however, suppressed if there's --prefix on the configure command line. Now, the problem is that we tried to construct path for wireshark plugin in the m4 file. Based on the knowledge described above, we shouldn't do it and just construct the full path in Makefile later where prefix has proper value.
