Subject: [PATCH] build: Remove outdated comment about -ffile-prefix-map

The -ffile-prefix-map option is no longer used and it seems fine to
remove the warning about it possibly breaking coverage builds.

If this needs documentation, the dev notes seem like a better place,
because it also affects other places, such as depends. C.f. commit
