In general you need to edit the rules file or files and a possible
install file, usually with an editor. For some packages this is easy
to do, gcc-4.9 is a "little" bit tricky. It's not just that configure
provides --prefix=, --libdir=, --libexecdir= etc., there's not just a
single debian/rules file. The wording "big patch" could be reworded to
"you need a lot to rewrite using an editor, before you can start
compiling and building the package".

It's not helpful to top post, after the first reply bottom posted,
especially since bottom/inline posting is preferred Ubuntu mailing list
etiquette.
