It may be a surprise that the derivation-specific variables are exported,# since this is just sourced by the wrapped binaries---the end consumers. This# is because one wrapper binary may invoke another (e.g. cc invoking ld). In# that case, it is cheaper/better to not repeat this step and let the forked# wrapped binary just inherit the work of the forker's wrapper 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.
