Because I plan to finish this up and send it down to autoconf-archive
asap as it's not the first time I have to get something like this ;)

That's definitely a problem I didn't think about, I was expecting POSIX
shell to support that, but I'll look for another way.

I have to double check that one but I think that if I were to quote that
it wouldn't expand properly.

The inner check is already cached, so I don't think there is much need
for adding one further cache…

But this actually made me think that we might as well just use
AC_SEARCH_LIB and rely on the value stored in the cache to begin with so
I'll send a different version in a moment.
