mercurial (2.1.1-2) deb_specific__no_optim_bdiff_armel.patch

From: Javi Merino <cibervicho@gmail.com>
Description: gcc-4.6 -O2 miscompiles bdiff in armel
 This patch disables optimizations for bdiff in -O0 so that mercurial
 works in armel while we fix it in gcc.
 .
 Mercurial says it's not their problem so they won't accept the patch.
 In any case, this has to be a temporal hack.
