Add a new make pattern for creating <file> from <file>.src at build time. Define the recipe as a macro in order to avoid replicating it for cases where it needs to handle subdirectories (creating <dir>/<file> from <dir>/<file>.src).
This can be used instead of the current approach to perform the similar step for file.in during ./configure by renaming the source file to file.src. This will avoid having to run ./configure just because of modifying a file depending on a variable set by configure. Prepare to have multiple files as source for the replacement patterns.
