We encounter this link failure:

/usr/lib/libkrb5.so so try adding it to the linker command line
/usr/lib/libkrb5.so: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
It occurs for two reasons:
1) an updated toolchain no longer allows indirect linking.
Although this failure was first detected in Ubuntu Natty, the
same change is planned for Debian Wheezy:
http://wiki.debian.org/ToolChain/DSOLinking
2) the osdep.o object in the c-client.a library references a
symbol in libkrb5.so. You can actually see that we pass -lkrb5
but since it's passed *before* c-client.a, the optimizer will
optimize that symbol out of the library, thus causing the undef
error.
The fix is to pass -lkrb5 to the *right* of c-client.a, so the
optimizer doesn't strip it out.
Patch follows.
