Dynamic linker error?

[Aditya Kousik]

So, my application has a libc_lxip dependency but I have yet to set up
anything network related. It just links it because of LIBS += libc_lxip.
But it tries to set up the entire network configuration which I haven't set
up and it crashes looking for a Nic driver.

My session does not use any major network calls at all. So, what causes
this cascade of setup that ends with up the nic?

Thanks,
Aditya.
