[Build-common-hackers] Bug#712729: cdbs: langcore.mk: support dpkg-buildflags' DEB_CFLAGS_MAINT_APPEND and similar

[Emilio Pozuelo Monfort]

Package: cdbs
Version: 0.4.121
Severity: wishlist

Hi,

The hardening instructions in the Debian wiki[1] currently suggest to
include dpkg's buildflags.mk if the maintainer needs to add/remove/override
something, since CDBS doesn't support it (for packages that don't need
to change any *FLAGS, CDBS works perfectly fine). I suggest that we make
langcore respect those flags so that one can simply do:

DEB_LDFLAGS_MAINT_APPEND = -Wl,-O1 -Wl,--as-needed

and CDBS will do the right thing.

See dpkg's magic in /usr/share/dpkg/buildflags.mk.

Regards,
Emilio
