[R] LIBARROW_MINIMAL, LIBARROW_DOWNLOAD, NOT_CRAN env vars should not be case-sensitive

[asfimport]

Hi, since arrow 4.0.0 I'm having trouble getting the lz4 codec installed on ubuntu 20.04. After installing arrow 4.0.0 via CRAN, I run 

install_arrow(binary = FALSE, minimal = FALSE) 

After this completes, then

arrow_available()
[1] TRUE

codec_is_available("lz4")
[1] FALSE

What can I do to help resolve this problem?

Neal Richardson / @nealrichardson:
It looks like arrow::install_arrow() isn't setting the necessary environment variables correctly. You can instead set LIBARROW_MINIMAL=false before installing and that will give you the full build. Note that you don't need to install_arrow() after doing install.packages("arrow"), install_arrow() is mainly a convenience for installing an nightly package or for reinstalling with different options (though sadly it appears not to be doing its job correctly there).
