Title:
   ceph: Does not respect compiler flags for Python extensions

Status in ceph package in Ubuntu:
  New

Bug description:
  [Impact]
  The packaging does not respect compiler flags when building the Python extensions, notably hardening flags like the stack protector, as well as frame-pointer.

  [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=for
  mat-security -fcf-protection

  It can be seen that this is already the case for the shared libraries,
  it is only the Python extensions that are missing flags.

  [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.
