Comment (by Sebastian Huber):

 There are a couple of BSPs which use -D flags:

 We should ban the use of command line defines.

 Getting rid of the `-D__ppc_generic` is easy. Getting rid of the
 `-Dppc405`, etc. is more difficult and there is some interaction with the
 GCC specs:

 {{{
 #undef CPP_OS_DEFAULT_SPEC
 #define CPP_OS_DEFAULT_SPEC "\
 %{!mcpu*:  %{!Dppc*: %{!Dmpc*: -Dmpc750} } }\
 %{mcpu=403:  %{!Dppc*: %{!Dmpc*: -Dppc403}  } } \
 %{mcpu=505:  %{!Dppc*: %{!Dmpc*: -Dmpc505}  } } \
 %{mcpu=601:  %{!Dppc*: %{!Dmpc*: -Dppc601}  } } \

 }}}
