Because in default libs there'ss R5 libnet.so.
And linking a replacment libnet.so against R5 one don't sounds a good 
idea, does it!?

More specificly, under vanilla R5, Be's libnet.so export a _res data 
symbol with a different size than ours (mostly because since ISC 
modified the _res_state struct concent), and gcc linker in this case, 
by default, choose the biggest, which is Be's.
But in fact it don't, and make our _res symbol imported from Be's 
libnet.so.

So, we make our libnet.so (and only this library) build with -nostdlib 
to explicitly tell the linker to link against only libroot.so.
But, I overlooked at gcc link options, and choose the incorrect flag, 
removing startfiles at same time.

Which changing the -nostdlib flag to -nodefaultlibs in libnet.so 
Jamfile fix, as starfiles are linked again now.
