Previously, GNU make would delete the implicit intermediate .a/.def files after building, see [1] for details.
Not deleting them does inflate the size of the build directory a little bit, but only very marginally (from 201 to 213 MB for a build with GCC for x86_64). By keeping them around, they are easier to inspect if debugging some aspect of them. (Although I haven't really needed to do this - this isn't the main motivation.) By not removing them, a build of mingw-w64-crt doesn't end with a huge wall of text of make doing "rm <all-implicit-files>", making it easier to observe the output of the other compile commands instead.
