Well, you could use a chroot on system A to build it against an older |
71 |
copy of the library. I can't find a stage3 with that range of glibc, |
72 |
though if you can still track down sources to piece together a |
73 |
toolchain, LFS 6.2 [1] is from right around that time frame (around |
74 |
'06-'07). If anyone has a 2007.1 range stage3 laying around, though, |
75 |
all the hard work's already done for setting up a perfect chroot as |
76 |
long as it plays well with a newer kernel (or if you can do the build |
77 |
in said chroot on system B), I've had issues with a too-new set of |
78 |
libraries on older kernels more than once, not sure I've tried the |
79 |
other direction. |
