config.status also doesn't fully expand the variables, though, which is
something that you'd want for this sort of application. Otherwise, you
have to know all of the possible ways in which one variable could
reference another so that you can set all of them (and you can only write
files that have a variable resolution system, although pkg-config does
have one). Note that the user can do things like
--libdir='${datadir}/foo' at configure time, even if it's not common.
So yes, you could use config.status, but only if it also had a flag that
said to fully expand the variables before substituting them in, and I
suspect that's a fair amount of change to the script.
