If you look at configure.ac in the git sources, you'll see that it uses 
curl-config, not pkg-config.  The former reports:

$ curl-config --libs
-lcurl -lnghttp2 -lidn2 -lssh -lpsl -lssl -lcrypto -lldap -llber -lbrotlidec 
-lbrotlidec -lz

Yaakov's build of earlier versions of curl used a patch 7.33.0-libdeps.patch to 
prevent the unnecessary libs from being listed.  He even had a comment at the 
beginning of the patch, explaining the reason for it: "These are needed only for 
static linking, but we build with --disable-static".
