Merge branch 'anders/diameter/make/OTP-9638'

* anders/diameter/make/OTP-9638:
  Dumb down release target to Solaris /usr/ucb/install
  Dumb down opt/release targets to make 3.80
  Minor tweaks and cleanup
  Need absolute -pa for bootstrap build
  Simpler release targets for src subdirectories
  Use secondary expansion for src subdirectory rules
  One makefile for src build instead of recursion
  Remove app dependency on compiler to avoid forced recompilation
  Move diameter_exprecs to compiler directory

+%% This module provide OTP's dict interface built on top of ets.
+%%
+%% Note that while the interface is the same as dict the semantics
+%% aren't quite. A Dict here is just a table identifier (although
+%% this fact can't be used if you want dict/ets-based implementations
+%% to be interchangeable) so changes made to the Dict modify the
+%% underlying table. For merge/3, the first argument table is modified.
+%%
+%% The underlying ets table implementing a dict is deleted when the
+%% process from which new() was invoked exits and the dict is only
+%% writable from this process.
+%%
+%% The reason for this is to be able to swap dict/ets-based
+%% implementations: the former is easier to debug, the latter is
+%% faster for larger tables. It's also just a nice interface even
+%% when there's no need for swapability.
