A standard process has these segments:

  text  = where the code lives
  data  = initialized data
  bss   = unitialized data
  stack = the stack ;-)

All variables which are not initialized will be put into the BSS by
ld, so that the startup code (which runs before main) can just zero
out this area.  A regular C program can always assume that the foo in

static int foo;

is initialized to 0.  There is no need for explicit initilaization due
to the fact that foo will end up in BSS.
