   9 # Shell script to build shared library versions of the modules; since
  10 # the change to the *ahem* "proper" import/export mechanism, this script
  11 # is much simpler.  It handles PowerPC and x86, too.
  12 #
  13 # This is called by the Modules/Makefile as $(LDSHARED):
  14 #
  15 # $(LDSHARED) foomodule.o -o foomodule$(SO)
  16 #
  17 # Could also be called as:
  18 #
  19 # $(LDSHARED)  readline.o  -L/boot/home/config/lib -lreadline -ltermcap \
  20 # -o readline$(SO)
  21 #
  22 # so we need to preserve the arguments, sort of.
  23
  24 # Make sure we got reasonable arguments.
