Just tried again with crosstools-ng 1.19.0.  I commented out the 
appropriate lines in my cc.ini file, but the build failed with...

" The following requested languages could not be built: d "

... in the build.log file.

Also, the instructions here 
(http://gdcproject.org/wiki/Cross%20Compiler/crosstool-NG) say:

"If druntime & phobos do not yet compile for your target you can 
disable them:

Start ct-ng menuconfig, go to "C compiler" and add 
"--disable-libphobos" to "Core gcc extra config" and "gcc extra 
config". "

While the "Core gcc extra config" option exists, "gcc extra 
config" does not.

The quest continues...
