With the commit that switched x86 to binutils 2.39,

  2022.12.28.22.04.46 christos src/share/mk/bsd.own.mk 1.1291

the amount of disk space used by a NetBSD-current/amd64 installation
has increased from about one gigabyte to more than four gigabytes.
Binaries appear to have grown across the board; for example, /bin/sh
went from 222K to 2.0M.

 Log Message:
 PR/57147: Andreas Gustafsson: Work around binutils 2.38+ relro
 issue with +2M size in every binary by setting max-page-size. This
 is the simplest fix; fixing this properly requires a lot more
 surgery, and upstream seems uncertain how to fix it properly.
