So jnthn asked on IRC for someone to get the NQP commit that causes the build to break and I think I got it
I set rakudo to build from rakudo commit 0fde4a1e375a26da8d7b511aafdb6174e934b757 and did Perl Configure.pl -- gen-parrot and watched the build failed as described. Then I started from NQP commit 6be8ad9fd52fe4b769e6ba92a0e3de24b2f971e9 and did git -- reset hard for each commit after it in the nqp directory until it failed. For NQP commit ba8bf9311b31bacfeb0fcf368ccdf33bd375fd58 I can do a "make clean; make" and nqp builds. For NQP commit 35db04446b64c1d8f0a88e7579c2bbd0b3c5f2ea, the very next one, "make clean; make" fails with the characteristic invoke() not implemented error. Ron
