What you could do is make targets for the different architectures.  You
could set variables specific to these targets.  Just remember that the first
target is the "default" one (specifying a specific first target named so
could prevent confusion):

# first target is the default
default: linux

linux:
  LIBS =

win32:
  LIBS = -lwsock32

Or you could use a define (which I believe is nicer seems nicer):

# specify -DWIN32 as a parameter to make to set this var
ifdef WIN32
    LIBS = -lwsock32
else
    LIBS =
endif

Of course if you want to have these decisions made without required actions
by the user, you will have to look at the environment some way, like Gisle
suggested.
