You didn’t use reportbug to file this bug report, so I cannot verify it 
from the list of dependencies, but it seems that you have 
pkgconf-bin:i386 installed on your system instead of pkgconf-bin:amd64. 
This is what causes pkgconf or pkg-config to default to the i386 flags.


A better workaround would be to call pkg-config or pkgconf but 
annotating the command with the architecture name, in your case 
x86_64-linux-gnu-pkg-config or x86_64-linux-gnu-pkgconf.

Bug#1028105:

[jsupertoot]

I am also having this problem I just wanted to add that on my machine if I
use:

$ pkg-config --dump-personality
Triplet: default
DefaultSearchPaths: /usr/lib/pkgconfig /usr/share/pkgconfig
SystemIncludePaths: /usr/include
SystemLibraryPaths: /lib /lib/i386-linux-gnu /lib/x86_64-linux-gnu
/lib/x86_64-linux-gnux32 /lib64 /libx32 /usr/lib /usr/lib/i386-linux-gnu
/usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnux32 /usr/lib64
/usr/libx32

As you can see, Triplet is "default" and there are only two dirs in
DefaultSearchPath. There is a file installed on my machine at
/usr/share/pkgconfig/personality.d/x86_64-linux-gnu.personality. The
contents of this file are as follows:

$cat /usr/share/pkgconfig/personality.d/x86_64-linux-gnu.personality

Triplet: x86_64-linux-gnu
DefaultSearchPaths:
/usr/local/lib/x86_64-linux-gnu/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig
SystemIncludePaths: /usr/include
SystemLibraryPaths:
/lib:/lib/i386-linux-gnu:/lib/x86_64-linux-gnu:/lib/x86_64-linux-gnux32:/lib32:/libx32:/usr/lib:/usr/lib/i386-linux-gnu:/usr/lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnux32:/usr/lib32:/usr/libx32

Note that all the expected information is present. So it seems I have the
correct file on my machine but pkg-config isn't "seeing" it for some
reason.

Pkg-config is version 1.8.1-1 and my architecture is amd64.

Bug#1028105: pkg-config:amd64 does not include necessary default search path

Package: pkg-config:amd64
Version: 1.8.0-12

  When I try to check for a package using pkg-config it is not
  able to find the package even that it is properly installed.
  Current output
  $ pkg-config --modversion gthread-2.0
  Package gthread-2.0 was not found in the pkg-config search path.
  Perhaps you should add the directory containing `gthread-2.0.pc'
  to the PKG_CONFIG_PATH environment variable
  Package 'gthread-2.0', required by 'virtual:world', not found

  Workaround
  $ env PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/usr/lib/x86_64-linux-gnu/pkgconfig/"
pkg-config --modversion gthread-2.0
  2.74.4

  Expected output
  $ pkg-config --modversion gthread-2.0
  2.74.4

  The problem is that pkg-config does not know anything about this directory
  since it is not present in its default search directories
  $ pkg-config --variable pc_path pkg-config
  
/usr/local/lib/i386-linux-gnu/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/i386-linux-gnu/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig

  I am using Debian GNU/Linux 6.0.12-1 (2022-12-09), kernel 6.0.0-6-amd64
  and libc6 2.36-7.
