Bug#1104506: librsb: tunes runtime for build machine

[Chris Hofstaedtler]

Package: librsb0t64
Version: 1.3.0.2+dfsg-7
User: reproducible-builds at lists.alioth.debian.org

Hi,

librsb records the size of the CPU caches at build time, and embeds 
that into the resulting binary. This info is apparently used by 
rsb__do_init_inner to tune the library. Obviously the CPU caches can 
be different on a users machine than what they were on the build 
machines.

It would seem good to detect the CPU caches at runtime, and stop 
embedding this info in the binaries.

Best,
Chris
