  # A number of steps in the autoconfig process implicitly assume that the build
  # system and the host system are the same. For example, library components
  # want to build and run test programs to determine the behavior of certain
  # host system elements. This is clearly impossible when crosscompiling. To
  # work around these issues, the --enable-malloc0returnsnull (or
  # --disable-malloc0returnsnull, depending on the host system) must be passed
  # to configure.
  #                                -- https://www.x.org/wiki/CrossCompilingXorg/
  #
  # Concretely, between the releases of libXext 1.3.2 and 1.3.3,
  # XORG_CHECK_MALLOC_ZERO from xorg-macros was changed to use the autoconf
  # cache, expecting cross-compilation environments to seed this cache as there
  # is no single correct value when cross compiling (think uclibc, musl, etc.).
  # You can see the actual change in commit 72fdc868b56fe2b7bdc9a69872651baeca72
  # in the freedesktop/xorg-macros repo.
  #
  # As a result of this change, if we don't seed the cache and we don't use
  # either --{en,dis}able-malloc0returnsnull, the AC_RUN_IFELSE block has no
  # optional action-if-cross-compiling argument and configure prints an error
  # message and exits as documented in the autoconf manual. Prior to this
  # commit, the AC_RUN_IFELSE block had an action-if-cross-compiling argument
  # which set the more pessimistic default value MALLOC_ZERO_RETURNS_NULL=yes.
  # This is why the flag was not required prior to libXext 1.3.3.
