 It looks like there is a spurious `dynamicroot' condition on the
 /usr/libexec/ld.elf_so entry, which should instead be unconditional.
 
 The condition may have been added by mistake by scole@ in 2016 for
 this PR to fix various ia64 build issues:
 
 https://gnats.netbsd.org/51261
 
 The PR has a comment about it suggesting it was intentional:
 
  M distrib/sets/lists/base/shl.mi		# change dynamicroot for ./lib/npf*, usr=
 /libexec/ld.elf_so
 
 But I don't think that makes sense, because /usr/libexec/ld.elf_so is
 always there (it's a regular file with MKDYNAMICROOT=3Dno, a symlink
 with MKDYNAMICROOT=3Dyes), whereas /libexec/ld.elf_so is correctly
 conditioned on `dynamicroot'.
