Title:
  pillow: Does not respect compiler flags

Status in pillow package in Ubuntu:
  Fix Released

Bug description:
  [Impact]
  The packaging does not respect compiler flags, notably hardening flags like the stack protector, as well as frame pointer, as it never uses dpkg-buildflags and is still old manual style.

  This means there is a higher security risk, and the lack of frame
  pointers hampers profiling.

  [Test plan]
  Look at the build log and see that the build flags have been passed, notably stuff like

  -fno-strict-overflow -Wsign-compare -DNDEBUG -g -O2 -Wall -g -O2
  -Werror=implicit-function-declaration -fno-omit-frame-pointer -mno-
  omit-leaf-frame-pointer -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-
  protector-strong -fstack-clash-protection -Wformat -Werror=format-
  security -fcf-protection

  [Where problems could occur]
  Hardening flags could surface existing (possibly security) bugs that have been asymptomatic so far; frame pointers will incur some slow down.
