# This is an "ar rcs" equivalent without "no symbols" warnings.
# Background:
#
# NuttX assumes that it's ok to create
#
# - An object without any symbols ("has no symbols")
# - A library without any symbols ("the table of contents is empty")
#
# While macOS's ranlib/libtool can handle those cases,
# it produces warnings cited in the parentheses.
# NuttX developers are not happy with those warnings.
# NuttX developers are not happy with providing per-library dummy
# objects either.
#
# The "has no symbols" warning can be suppressed with
# the -no_warning_for_no_symbols option if you are using
# a recent enough version of ranlib/libtool.
# (Unfortunately, ar doesn't have a way to pass the option to ranlib.)
# However, there seems to be no way to suppress the
# "the table of contents is empty" warning. (thus the grep below)
#
# Reference:
