IME, the only way to debug mysterious builtin failures is to add
temporary debug logic to the builtin.mk file to report what's going
on, and test it from the client package using make -V or make
show-var. (Remember also to make clean in the client package before
experimenting, or you can waste a lot of time being shown out of date
cached values.)
