I don't really know.  Here are the text symbols it defines:

 __chk_fail
 __stack_chk_fail
 __stack_chk_fail_local
 __gets_chk
 __memcpy_chk
 __memmove_chk
 __mempcpy_chk
 __memset_chk
 __stpcpy_chk
 __strcat_chk
 __strcpy_chk
 __strncat_chk
 __strncpy_chk

My guess is it's some internal uClibc stuff.

Nothing that I happen to be building (as far as I know).

I don't know.  Does it matter?

OK.

Why not run "ldd" on the binaries in output/target/bin and
output/target/usr/bin and just copy whatever libraries they need?

Does buildroot need to know exactly for what a library is used by each
binary?
