[Bug 1980494] Re: krb5-multidev is not multi-arch installable due to differences in /usr/bin/krb5-config.mit

[Steve Langasek]

I think the right fix here is to strip the output of dpkg-buildflags
from the config script output.  We've definitely had problems before
where leaking dpkg-buildflags into other build tools made it effectively
impossible for dependent packages to work around toolchain issues.

Title:
  krb5-multidev is not multi-arch installable due to differences in
  /usr/bin/krb5-config.mit

Status in krb5 package in Ubuntu:
  New

Bug description:
  I am trying to build wine in a wow64 configuration and need to install
  the i386 and amd64 version of the krb5-multidev package on Ubuntu
  22.04.  The two version are not co-installable due to differences in
  the /usr/bin/krb5-config.mit file between the two version of the
  package.

  The diff between the two files is:

  --- krb5-config.mit-i386	2022-06-18 21:32:44.034889873 -0400
  +++ krb5-config.mit-amd64	2022-06-18 21:31:37.302149522 -0400

  The krb5-multidev package is co-installable on Debian. It appears that
  Ubuntu uses different default linker flags for the i386 and amd64
  platforms and Debian does not.
