Wait a minit. The part of ldd's output which follows after "=>" shows the
path where the lib on the left side of "=>" is actually resolved. If you
take your binary to a machine where uClibc is installed in
/foo/lib/uClibc, then you will see ldd showing:

libc.so.0 => /foo/lib/uClibc/libc.so.0
/usr/lib/ld-uClibc.so.0 => not found

-- as the latter one is an absolute path and cannot be resolved. So in
your case, the path /build/uClibc/usr/lib is not hardlinked to your
binary, so I think there is no problem, but you will not see 

libc.so.0 => /usr/lib/libc.so.0 (0x0x40006000)
ld-uClibc.so.0 => /usr/lib/ld-uClibc.so.0 (0x0x40000000)

'till you won't install uClibc to /usr/lib. But I think this is not wha
you want.
