[Build-common-hackers] Bug#651966: class/langcore.mk: DEB_BUILD_MAINT_OPTIONS not passed to dpkg-buildflags

[Simon Ruderich]

Package: cdbs
Severity: important
Tags: patch

Hello,

To modify hardening flags dpkg-buildflags uses the
DEB_BUILD_MAINT_OPTIONS environmental variable. For example to
enable all hardening flags the maintainer can set it in
debian/rules:

    export DEB_BUILD_MAINT_OPTIONS=hardening=+all

    include /usr/share/cdbs/1/...
    ...

But $(shell ...) doesn't inherit exported variables, thus at the
moment it's not possible to use DEB_BUILD_MAINT_OPTIONS to modify
dpkg-buildflags hardening flags in cdbs.

The attached patch fixes this and passes DEB_BUILD_MAINT_OPTIONS
to dpkg-buildflags, but I'm not sure if it's the best way to do
it.

Regards,
Simon
