Bug#834706: libc6-dev: needs versioned dependency on linux-libc-dev for SYS_getrandom

[Lionel Elie Mamane <lionel@mamane.lu>]

Package: libc6-dev
Version: 2.23-4
Severity: serious
Justification: Policy 3.5

/usr/include/x86_64-linux-gnu/bits/syscall.h
contains
#define SYS_getrandom __NR_getrandom
but that is not defined in stable's linux-libc-dev (version
3.16.7-ckt25-2 and security update 3.16.7-ckt25-2+deb8u3).

For this #define to work, libc6-dev needs a versioned depends on a
newer version of linux-libc-dev. The version now in sid and testing
(4.6.4-1) works but probably the requirement is more lax than that.
