Bug#1016904: boost1.74: Please include patch to fix FTBFS on qemu-user

Source: boost1.74
Version: 1.74.0-16.1
Severity: normal
Tags: patch

Hello!

boost1.74 currently FTBFS on m68k and sh4 due to a filesystem compatiblity
issue that is present on qemu-user [1]. Both m68k and sh4 use qemu-based
buildds which is why these architectures are affected by this problem.

Upstream has come up with a workaround for the problem which is present in
newer versions of the b2 utility [2].

Could you backport the patch to boost1.74 so that the builds get fixed on
m68k and sh4?

Please see the attached patch.

Thanks,
Adrian
