I'm puzzled by the reported failure of "install_root" to do what 
it's supposed to. I've been using that formulation for years, to 
install new builds of glibc into /tmp/glibc-N.M from where I make a 
tarball, which I subsequently untar into the system location using a 
bootable CD (SystemRescueCd). This worked fine for me with glibc 
2.15. I use the invocation, for example,

make install_root=/tmp/glibc-2.15 install

and nothing spills into system locations. I don't mind using DESTDIR 
instead; I just don't understand the complaint.
