Yes, I agree.

"build.sh install=..." is not the same as "make install" or
"${TOOLDIR}/bin/nbmake-${MACHINE} install".  The instructions which you
quoted (and which I elided) are about using build.sh to install, and
I agree that, at the build.sh level, it's important for "install=/"
to be independent of "-U".  It's not at all clear to me that the same
reasoning applies at the nbmake-${MACHINE} level.
