[Lazarus] Build Lazarus with Clean all - cleaning packages

[cobines]

Shouldn't the package files be rebuilt automatically? For example
package "A" depends on LCL. The LCL source files change and LCL
package is rebuilt manually or automatically (*.o, *.ppu change). Then
you rebuild package "A" and the files that use the changed files
should be rebuilt. But they are not and it is required to delete them
first.

Or it doesn't work like that?
