It is supposed to be set by the previous option (--libdir).
Just like there is no PREFIX env var, but it is the value set by the
--prefix option.

Probably "[same as --libdir]" would be easier to understand, but it
would not be consistent with the rest of how [] is used in configure
help. And if you go that way, how would you describe the --libdir
default?

"[ --prefix/lib]"
"[ ${--prefix}/lib]"
"[ ${prefix}/lib]"
"[$prefix/lib]"
"[$PREFIX/lib]"
"[PREFIX/lib]"

Hum, actually, I kind of like the 3'd  one.

autoconf handles a single --libdir and people do expect that other
configures work in a similar way.

Please, commit your current patch.

BTW, another possible solution is to remove --shlibdir entirely. Is
that option even used/useful?
