No, it doesn't. Your change changes pre-installation of these files from
"installation-on-the-fly" to "forced pre-installation".

That's exactly the point needing to be investigated.

Therefore: Which part of RTEMS code makes you say this? I don't see it.

It shouldn't do any harm.

To be investigated. I recall this kind of bug being present in an older
snapshot, but I thought I had fixed it.

I need to look into the source-code. I could have missed something, it
could be a packaging bug, could be problems with autom4te.caches.
