Subject: make-4.2-1; seeing new "No rule to make target" errors with parallel builds

Marco and anybody else,
Has anyone been seeing issues with the latest make version on big
parallel compiles? I'm having trouble with LLVM for example, which
I've been building every few days or so on older versions of make
with no trouble. e.g.
curl -LO http://llvm.org/releases/3.7.1/llvm-3.7.1.src.tar.xz
tar -xJf llvm-3.7.1.src.tar.xz
mkdir llvm-3.7.1.src/build
cd llvm-3.7.1.src/build
../configure CC=gcc CXX=g++ # it defaults to clang but that's broken
make -j8
This works perfectly when I downgrade to make 4.1-1. On latest 4.2-1,
I get https://gist.github.com/a9322320eb73f9c3b56f6b732785d8a4
... (about 12 minutes in) ...
make[2]: Entering directory '/home/Tony/github/llvm-3.7.1.src/build/tools/lto'
make[2]: *** No rule to make target
'/home/Tony/github/llvm-3.7.1.src/build/Release+Asserts/lib/libLLVMBPFCodeGen.a',
needed by
'/home/Tony/github/llvm-3.7.1.src/build/Release+Asserts/bin/cygLTO.dll'. Stop.
make[2]: *** Waiting for unfinished jobs....
make[2]: Leaving directory '/home/Tony/github/llvm-3.7.1.src/build/tools/lto'
make[1]: *** [/home/Tony/github/llvm-3.7.1.src/Makefile.rules:880: all] Error 1
make[1]: Leaving directory '/home/Tony/github/llvm-3.7.1.src/build/tools'
make: *** [/home/Tony/github/llvm-3.7.1.src/Makefile.rules:880: all] Error 1
Maybe there's a bug in LLVM's dependency declarations here that just
gets triggered by the newer version of make? Continuing with make -j1
seems to go through on make 4.2, but was never necessary on 4.1.
My cygcheck.out is at (can't do attachments from gmane)

Thanks in advance,
Tony
