Please add support to enable to build with frame-pointer turned on. The
compilers in unstable default to -fomit-framepointer, this turns on
-fno-omit-framepointer plus an architecture specific option.

To enable it, use

    DEB_BUILD_MAINT_OPTIONS="... qa=+framepointer"

The chosen area might not be ideal, it could also be added to the
optimize area, however it is a "negative" optimization.

Currently the default is not changed in Debian.

I would even love to have finally a debian again which can be used to
debug and profile production ready binaries (at least on amd64). See
