The idea is that e.g. pkgconf:amd64 provides /usr/bin/x86_64-linux-gnu-pkg-config, which is a symlink to pkgconf, and /usr/share/pkgconfig/personality.d/x86_64-linux-gnu.personality, which defines DefaultSearchPaths and SystemLibraryPaths to be appropriate values for amd64. pkgconf:amd64 itself doesn’t ship a pkgconf binary, which is, instead, provided in pkgconf-bin, a Multi-Arch: foreign package.
pkgconf detects that it’s run using a symlink, and uses it to select the matching personality, and then provides results based on these settings.
So, unless I’ve messed up with the multi-arch stuff, it should be enough to install pkgconf:<arch> to cross-build packages.
