I thought about inverting the logic since Gyp was originally meant to be able 
to support out-of-tree builds by starting in the
build directory.

That can make use of the configure "--srcdir" option and Make's $(srcdir).

Unfortunately, despite several hours messing about with it, because of some 
Chrome-specific hacks to Gyp involving the "--depth" option, I've found no way 
to persuade Gyp to write the
node*{target,host}.mk files to the build directory. Instead it writes them to a 
relative path calculated based on the source's location but applied to the 
build directory - which ends up creating an
entire new directory hierarchy in some random grand-parent of the build 
directory.

I'll take another look at this approach when I have more time but for now my 
current patch works for building. I noticed whilst investigating "--srcdir" 
options that I've missed some paths in the
Makefile for some of the doc and test targets; I'll deal with them this weekend.
