Thanks for an explanation. At least some of it should be in commit
message, to explain what you want the patch to do.

I don't know autotools enough to check if autotools (autoconf) doesn't
have it's own way to do this, some autoconf macro, to not need to write
this script creating redirect Makefiles.

I'm still not sure if this has place in git. Is it really common to
support building outside source directory? If git didn't support this,
so what?
