[Bug 2077744] [NEW] pillow: Does not respect compiler flags

[Graham Inggs]

Public bug reported:

[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.
