Right.  This is why the instructions in README

  build="$(build-aux/config.guess)"
  ./configure --prefix=TARGETDIR --host=TARGET --build=$build
  cd src
  make gen-posix-lock-obj
  scp gen-posix-lock-obj TARGET:
  ssh TARGET ./gen-posix-lock-obj >tmp.h
  mv tmp.h "syscfg/$(awk 'NR==1 {print $2}' tmp.h)"

say to build and execute gen-posix-lock-obj for the targeted host.
This needs to be done just once and then we can include the required
info into the release.  For Debian the fastest way forward is to follow
the instructions and include a patch for each platform.

By means of configure's AC_CHECK_SIZEOF - pretty standard for
cross-compiling.
