Bug#796906: fails to build stage1 cross compiler for m68k
Source: gcc-5
Tags: patch
User: helmutg@debian.org
Usertags: rebootstrap
m68k implements does not have hardware supported atomics, so it falls
back to linux syscalls to implement atomics on that architecture even
when one builds a stage1 (without libc). However the Build-Depends do
not reflect that. Building the stage1 cross compiler for m68k without
linux-libc-dev installed results in the following error:

I have not seen a similar error for any other architecture.
Thus I am proposing to add that dependency just for m68k, which is
implemented in the attached patch. Please consider applying it.
