Bug#1063734: no -D_TIME_BITS=64 on builds where t64 support is supposed to be done

[Rene Engelhard]

Source: gnutls28
Version: 3.8.3-1.1~exp1
Severity: important

[ let's no get into a discussion on  the sense of this transition. I 
actually believe this isn't needed and we can leave 32 bit die in 2038 
but anyways...

The transition is ongoing now in experimental. So be it ]

Hi,

I just tried a rebuild of libreoffice with 
DEB_HOST_MAINT_OPTIONS="abi=+time64" to actually see what happens.

It failed in a certificate unit tests so I tried to rebuild the 
"certificate" related (build-)dependencies also with 
DEB_HOST_MAINT_OPTIONS="abi=+time64"

While doing so I noticed that gnutls28 doesn't define -D_TIME_BITS=64 
even when built for t64 (as in the experimental NMU renaming to t64) on 
the affected architectures (anything 32-bit except i386).

This is probably because it doesn't honout dpkg-buildflags.

But even if you don't like dpkg-buildflags that define has to be done.

Regards,

Rene

P.S::
Thankfully libreoffice is fine with just xmlsec1 being rebuilt. But it 
uses the nss flabour, so stuff using gnutls might break, no idea
