hadrian/make difference, you can pass --docdir, --prefix etc to initial ./configure with make (but not hadrian)

Sterni points out that with make you can run

./configure --prefix=/foo
make install

And the arguments to ./configure will also apply to the install configure script.

With hadrian the two scripts are completely separate so you have to pass --prefix=/foo to the install configure script. There is the ./hadrian/build install --prefix=/foo command which attempts to work around this a bit just for the --prefix configure option but other options like --docdir are just ignored by the initial configure script.

I think the new behaviour is right but just noting this issue in case other people run into it.
