I investigated this a bit and found that the JDK is not really needed at
build time.  The first patch includes a comment explaining why we
dropped the JDK from the inputs.

The second patch adds build phases to install the info documentation.

Removing texlive is possible as well, but it results in the loss of the
following files:

./lib/R/library/grid
  /doc
    displaylist.R
    displaylist.Rnw
    frame.R
    frame.Rnw
    grid.R
    grid.Rnw
    grobs.R
    grobs.Rnw
    index.html
    interactive.R
    interactive.Rnw
    locndimn.R
    locndimn.Rnw
    moveline.R
    moveline.Rnw
    nonfinite.R
    nonfinite.Rnw
    plotexample.R
    plotexample.Rnw
    rotated.R
    rotated.Rnw
    saveload.R
    saveload.Rnw
    sharing.R
    sharing.Rnw
    viewports.R
    viewports.Rnw
  /Meta
    vignette.rds

./lib/R/library/parallel
  /doc
    index.html
    parallel.R
    parallel.Rnw
  /Meta
    vignette.rds

./lib/R/library/utils
  /doc
    index.html
    Sweave.R
    Sweave.Rnw
  /Meta
    vignette.rds

Note that these Rnw files are all literate programming sources
containing the sources that are untangled to .R files and the PDF
documentation.  Interestingly, the source tarball already contains the
PDF files (e.g. the one installed to
“lib/R/library/grid/doc/viewports.pdf”), so we don’t need texlive to
generate them.

Attached are the three patches.
