Other than this .pc file, the -dev package only contains D-Bus
introspection XML (from which other packages can generate code);
so it seems better to use --libdir=/usr/lib (to avoid per-arch
variation - the ${libdir} is mentioned but unused), move the
.pc file to /usr/share/pkgconfig, and keep it M-A: foreign.

xdg-desktop-portal-dev has more in common with, for example,
x11proto-core-dev than it does with libflatpak-dev.

I'll send patches upstream to cut out the bits that have clearly
been cargo-culted from a library's pkg-config metadata.
