Re: Eliminating more recursive make invocations

FYI,

Under the new build system it is more difficult, but still possible to
re-build just a single file.  I've been working on the m-files that
generate the images for the Manual and as soon as you touch one it re-makes
all the images in the file (7) with four different extensions (.txt, .png,
.pdf, .eps).  This is super slow and bad for my testing purposes.

Here is an example that shows the general scheme for re-building a single
file; Use -C followed by the relative path to the top-level directory and a
relative path from the top-level to the file to rebuild.

make -C ../.. ./doc/interpreter/extended.pdf

Hope this helps someone else.
