For the record, there is a "pkgconf", see:
 https://git.sr.ht/~kaniini/pkgconf

and there is a debian package for it as well as pkg-config:

$ apt-cache show pkgconf |head -3
Package: pkgconf
Version: 1.6.0-1
Installed-Size: 300
$ apt-cache show pkg-config |head -3
Package: pkg-config
Version: 0.29-6
Installed-Size: 203

So you don't have to patch the makefile, just update your build 
dependencies.
