make install fails when .requirements.txt is empty

[karras]

make install fails when .requirements.txt is empty:

$ make install
touch .requirements.txt
pip install --upgrade -r .requirements.txt
You must give at least one requirement to install (see "pip help install")

Nevermind, just added the package itself to .requirements.txt. :S

@karras that is new. It used to work with a empty file. I don't see a good solution yet.
