I think the answer to that is no. The changes appear to be threading
related. I'm guessing here, but I wouldn't be surprised if 2.4.20
introduced NPTL support.
With 2.4.2 "ldd /bin/cat" gives:
libc.so.6 => /lib/obsolete/linuxthreads/libc.so.6 (0x4806b000)
/lib/ld-linux.so.2 (0x4804d000)
With 2.4.20:
libc.so.6 => /lib/libc.so.6 (0x4806b000)
/lib/ld-linux.so.2 (0x4804d000)
The question is then why /bin/ls doesn't pick up the librt.so in
/lib/obsolete/linuxthreads. Firefox for instance picks up a few from
this directory.
libpthread.so.0 => /lib/obsolete/linuxthreads/libpthread.so.0 (0x489bd000)
libm.so.6 => /lib/obsolete/linuxthreads/libm.so.6 (0x48fa1000)
libc.so.6 => /lib/obsolete/linuxthreads/libc.so.6 (0x49151000)
The easiest solution is probably to copy
/lib/obsolete/linuxthreads/librt-2.3.6.so to /lib.
