Here's the relevant part of a pkg-config file produced during make:

prefix=/usr
exec_prefix=/usr
libdir=/usr/lib
includedir=/usr/include

Versus during configure:

prefix=/usr
exec_prefix=/usr
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Which disproportionately affects cross-compiling and similar build situations.

OpenWrt includes an equivalent change for kmod (which Lucas mentioned
as I've submitted it upstream), and without an upstream change will
have to carry one for systemd too.

Finally, a supporting appeal to authority: If you check GNOME-land,
practically all pkg-config files are generated at configure time. :-)
