Bug#822189: gcc-5-multilib: asm/errno.h not found for non-default architecture

[Hilko Bengen <bengen@debian.org>]

Package: gcc-5-multilib
Version: 5.3.1-14
Severity: important

Dear Maintainers,

when trying to build i386 binaries using gcc-5-multilib on an amd64
host, <errno.h> includes cannot be resolved.

,----
| $ echo '#include <errno.h>' | gcc -m32 -E - > /dev/null 
| In file included from /usr/include/bits/errno.h:24:0,
|                  from /usr/include/errno.h:35,
|                  from <stdin>:1:
| /usr/include/linux/errno.h:1:23: fatal error: asm/errno.h: No such file or directory
| $ echo '#include <errno.h>' | gcc -m64 -E - > /dev/null 
| $ 
`----

gcc-multilib used to provide a symlink for /usr/include/asm (in my case
to x86_64-linux-gnu/asm). Restoring that symlink would fix the problem I
observed.

Cheers,
-Hilko
