Nice trick, but what about the slightly-more readable;
printf 'PATH="$${PATH}:/usr/lib/node_modules/.bin"\n' \
>$(TARGET_DIR)/etc/profile.d/node_modules.sh
- because this is in a Makefile, so we need to $-escape the $.
- because we do not want that $ to be interpreted by the shell (at build
time!), we single-quote it.
- because whoever knows what PATH is made of would be a fool (and
because the world is cruel), we double-quote it (at runtime!)
Otherwise, what is the reason to have nodejs modules available as
commands from a login (!) shell? (Note: nodejs-noob speaking!)
