good to know your longterm plan :)
however, even if both can be done, i still don't see the point of going
through patching if we end up changing the default anyway.

maybe the fact that some file operations are broken with glibc's
default settings on a somewhat popular fs would be a good argument to
un-stall it ?

yes, but that is not what i am discussing: unless i missed something,
they'll all end up one way or another adding the relevant defines;
whether it is done with an m4 macro, append-lfs-flags, a cmake function
or what else is an implementation detail of little interest to me trying
to understand why we don't simply change the default :)
