I think it needs to be limited to:

  OS/distribution/ known to use ldconfig
  running as root
  no DESTDIR setting (packaging systems often build to staging)

and I'm not really sure this belongs in 'make install' anyway, vs people
who use systems that want ldconfig running it after installation -- but
I'm not clear on existing practice.

As long as it doesn't get run if any of the 3 are false, won't bother
me.
