[BusyBox] Compiling busybox NFS-capable mount with uClibc

[David Douthitt]

I tried to compile busybox, and got an error.  This is the first time
compiling with NFS capabilities in mount.  I'm compiling the August 9
2001 CVS tarball, and using uClibc.

This is the error I got:

If I understand this right, these symbols are all in libc.so.6 (glibc
2.1); they apparently are NOT in uClibc.
