# Contains Debian-specific options --override-* added by the patch
# d/p/override-uname.patch, which fixes a reproducible build.
# A method based on command substitution is used to ensure that the
# configuration flags in the nginx-dev package are architecture-independent.
# The same approach is applied to the --with-cc-opt and --with-ld-opt options.
# Note: the value --override-release=3.16.0 is the minimum kernel version we
# expect the compiled nginx binary to run on (Debian 8).
