# To support this use case we need to link statically as we will be unable to
# locate libc.so at run time if it's not installed in /lib.
#
# We support building ostree-prepare-root with a different compiler to the rest
# of ostree so we can use musl rather than glibc. This reduces the size of the
# executable significantly: from ~700K -> ~30K. We have to use _SCRIPTS here
# to get autotools to install this as an executable but without generating rules
# to make it itself which we have specified manually. See
# https://lists.gnu.org/archive/html/help-gnu-utils/2007-01/msg00007.html
