Different configurations such as different compiler command-line
arguments, linker options, etc.

If you build Postfix twice without changes, then the builds are not different.

That should work, assuming there are no significant changes in the
build infrastructure or installed libraries (Postfix by default
tries to auto-detect ICU and PCRE support, so results may differ).
Just to be sure, compare your makedefs.out file with the one installed
in $meta_directory/makedefs.out.
