Glibc is compiled by GCC.  The libs are linked with libgcc_s.so.0.  As noted before:

$ ldd math/libm.so.6 
        libc.so.6 => /lib/libc.so.6 (0x4001c000)
        libgcc_s.so.0 => /opt/gcc-2.97.test/lib/libgcc_s.so.0 (0x4012f000)
        /usr/src/test/glibc-2.2/lib/ld-linux.so.2 => /usr/src/test/glibc-2.2/lib/ld-linux.so.2 (0x40000000)

This causes major problems if libgcc_s is not on the same partition as
libc.so.6.

Please reread the thread, the whole situation is rather complicated.
