# Export and assign separately in order that a failing $(..) will fail
# the script.
# Currently bootstrap-tools does not split glibc, and gcc files into
# separate directories. As a workaround we want resulting cflags to be
# ordered as: crt1-cflags libc-cflags cc-cflags. Otherwise we mix crt/libc.so
# from different libc as seen in
# https://github.com/NixOS/nixpkgs/issues/158042
#
# Note that below has reverse ordering as we prepend flags one-by-one.
# Once bootstrap-tools is split into different directories we can stop
# relying on flag ordering below.
