There is one:

You could create lrs files from arbitrary files:

compile tools/lazres.lpi to create tools/lazres

./tools/lazres your.lrs your1.something your2.something ...

You can update them manually or write a script/program and execute that
before package compile.

Maybe this works for you:
Create a package (e.g. yourtool), add the source of your program,
uncheck 'use unit'.
Then put the command to compile into the 'after compilation step': 
fpc yourprogram.pas -FE$PkgOutDir(yourtool)/
and check 'Scan for FPC messages'.
Then add yourtool as requirement to your main package.
Whenever your main package is compiled, the yourtool package is
compiled too, which automatically compiles your tool.
