Bug#1133272: dpkg-buildflags: please include LFS_CFLAGS and LFS_LDFLAGS

Package: dpkg-dev
Version: 1.23.7
Severity: important
X-Debbugs-Cc: [email protected]

In my packages, I currently have to manually include the following in debian/rules:

export DEB_CFLAGS_MAINT_APPEND  +=$(shell getconf LFS_CFLAGS) $(HARDENING_CFLAGS)
export DEB_LDFLAGS_MAINT_APPEND +=$(shell getconf LFS_LDFLAGS) $(HARDENING_LDFLAGS)

It would be nice if dpkg-buildflags provided these for us.

Thanks!
Martin-Éric
