I have seen the same message for libusb both with gcc 4.4.4 and 4.3.3
Note that libc.so is in usr/lib while the lib.so.6 file is in lib.
No idea if that is relevant.

libc.so contains:
frans at linux-suse:~/oe/tmp_angstrom/sysroots> cat
./armv7a-angstrom-linux-gnueabi/usr/lib/libc.so
/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
OUTPUT_FORMAT(elf32-littlearm)
GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a  AS_NEEDED (
/lib/ld-linux.so.3 ) )

No idea if these should be paths in sysroots (I'm not a dynamic linking expert).
