You are right, that would be better. My understanding is that
pkg-config files are supposed to define variables in terms of 'prefix'
as described in pkg-config(1)
--8<---------------cut here---------------start------------->8---
prefix=/home/hp/unst # this defines a variable
exec_prefix=${prefix} # defining another variable in terms of the first
libdir=${exec_prefix}/lib
includedir=${prefix}/include
--8<---------------cut here---------------end--------------->8---
but “systemd.pc” isn't doing that.

Every default installation directories are expected to be subdirectories
of the 'prefix' variable. This is verified by ‘make distcheck’ and
specified in GNU coding standards:
https://www.gnu.org/prep/standards/html_node/Directory-Variables.html#Directory-Variables
So it is unlikely that a patch is going to be accepted in Automake.
However I guess the default pkg-config file could be fixed in Systemd.
