fix for arm target.ld

[Robin Farine]

The tool chain I'm using calls the preprocessor with -Darm by default
(stupid, I know, but ..it happens) and thus transforms ".note.arm.ident"
into ".note. 1 .ident".

To generate "target.ld", each architecture provides it own set of CPP
macros so I thought that this precise case doesn't need the
automatically provided architecture CPP flags. Moreover, if an
architecture needs some flags during this step, the CDL file could
explicitly define them.

But hey, if this patch causes any problem, please feel free to open the
(trashcan) window and throw it away, I'm just trying to respect the
terms of the GPL (of which I don't understand much, lawyer stuff ... ok
time to click "send")
