Under those conditions, there's quite possibly a libstrl already installed
without a strl.h, so trying to install our own libstrl would cause a
filename collision and an install failure.

I'm not too keen on peppering people's installations with a variety of
strlcat/strlcpy implementations. We probably shouldn't do this.

By that you mean install strl.h if there isn't one, even if you're not
installing the library?

Wouldn't that cause runtime failures or build failures, since that would
mean those functions go unresolved?

A fourth option would be to force our libstrl to be static, always link
against that, and never install it.

A fifth option would be to provide documentation that we got 2.7.1 wrong
by not installing strl.h, and have people manually remove our libstrl from
those installations before doing "make install" for 2.7.2 or later, if
they want those warnings to go away.
