Subject: [PATCH 1/9] Gentoo: ld: always warn about textrels in files

textrels are bad for forcing copy-on-write (this affects everyone), and for
security/runtime code generation, this affects security ppl.  But in either
case, it doesn't matter who needs textrels, it's the very fact that they're
needed at all.

(cherry picked from commit cd6411ad57aab78686f67cbbc1ed70ee810ad335)
