Well, you could use a chroot on system A to build it against an older copy of the library. I can't find a stage3 with that range of glibc, though if you can still track down sources to piece together a toolchain, LFS 6.2 [1] is from right around that time frame (around '06-'07). If anyone has a 2007.1 range stage3 laying around, though, all the hard work's already done for setting up a perfect chroot as long as it plays well with a newer kernel (or if you can do the build in said chroot on system B), I've had issues with a too-new set of libraries on older kernels more than once, not sure I've tried the other direction.
