iphone + D, getting closer!

[Dan Olson]

Ok, D is not there yet, but I managed to build a crippled gcc-4.8 (with
D) targeting arm-apple-darwin and I can compile simple C functions to .o
files and link them into an iphone app.  And run it on my iphone.  The D
and C++ compilers built, but I have probably a potpourri of issues since
I gave 4.8 a arm-darwin target by selectively copying apple's 4.2
changes for arm-darwin.  gcc-4.8 was configured to use tools (as, ld) in
the apple iphone SDK.

The biggest hassle is that apple's version of arm as is different than
binutils as.  So I am learning what it wants for debug and pseudo op
differences.

Even a simple D module with just a extern(C) function depends on
something in druntime, so I have to get part of that to build first.
