Message:

1. Getting LIBJPEG to compile on Mac requires not passing --enable-static. On Mac too, compiling LIBJPEG also only produces .a (and no .so/.dylib) no matter what, but that happens to be what we want anyway. 2. Turning off building shared libraries (--disable-shared) for all libraries we build that are used by xpdftools, so that on Mac it hopefully chooses to link these in (which won't happen if there's a preferred dylib elsewhere, particularly on the system, which will then get linked in in preference on Macs). Still need to test these changes on Linux again.

+D. On why you can't build static binaries on Mac, but can build static libraries and link against them

+https://dropline.net/2015/10/static-linking-on-mac-os-x/ (explains that on Mac, .dylibs must be hidden for .a versions of libraries to be selected when linking)
+    This means that where possible we want to essentially do "--enable-static --disable-shared", or equivalent, when generating freetype, libz, libpng, libjpg, libtiff library files
+    so that Xpdf-Tools links against the .a files we generated rather than additional .dylib files

+configuration options for building libtiff. Want to turn off the compile process for libtiff producing tiff binaries, but there appears to be no such option.
