Subject: [PATCH] add back a configure target

Otherwise, make reconfigures every time and then rebuilds all files.

I went too far in 3af9f5ed1a54f1df12f85f613826040e5e855817. All that's
needed is to make the configure target not use Build/SysConfig.hs as the
target name, so make won't delete that file after a failed build.
