Title:
  make: source build ignores debug in DEB_BUILD_OPTIONS

Status in make-dfsg package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: make

  After
      $ sudo apt-get build-dep make
      $ apt-get source make
      $ cd make-dfsg-3.81
      $ DEB_BUILD_OPTIONS="debug nostrip noopt" logsave ../make-debug.log dpkg-buildpackage -uc -us -rfakeroot

  I noticed that the source files were being built with "-O2" instead of "-O0".
  A comparison with the "remake" package (which behaves as expected) revealed that the environment setting made by dpkg-buildpackage was being stepped on by debian/common/copt.mk

  I created a patch as per
  https://wiki.ubuntu.com/PackagingGuide/Howtos/PatchingWithoutPatchSystem?highlight=(CategoryPackagingGuide)

  and have tested it locally - debugging builds work as expected -
  please find the patch attached.

  Unfortunately make must first be converted to use dpatch before this patch can be incorporated into the distribution.
  "remake" uses dpatch and supplying a "dpatch" patch is all that's required with that package.
