aha, it's a PIE (worked fine on ET_EXEC here).

this was the entry that paxctl complained about, and for a good
reason: filesz > memsz which while causes no apparent problem on
loading the binary, is still not good because it means the linker
put something into the file which will not be loaded into memory
at runtime (or rather, it will be in this particular case, but it
still points at a bug somewhere in the linker). i suggest you open
a (gentoo) bug on this (post the binutils version and readelf -e
at least).
