Because environ is defined in /lib/crt0.o which is automatically
included by CC when it runs LD.  That is why it is not recommended
that you run LD yourself.  Most of the time (like 99.99999% of the time)
using CC will do everything you need.

Even if you had gotten beyond the environ stuff you probably wouldn't 
of had a working executable because of no program startup code (which is 
also in crt0.o.

Note that the name of the startup file (crt0.o) changes depending upon 
your compilation environment (For ex: a posix load will use crtp0.o)
