# Makefile for Libsystem
# Call Makefile to do the work, but for the install case, we need to
# call Makefile for each arch separately, and create fat dylibs at the
# end.  This is because the comm page symbols are added as a special segment,
# which the linker will not thin, so we have to build thin and combine.
