This patch allows to specify -Tdata and -Ttext on the command line for MCUs
where the specs file sets these options. For -mmcu=atmega88 for example, the
respective specs reads:
*link_data_start:
-Tdata 0x800100
and the patch changes this to
*link_data_start:
%{!Tdata:-Tdata 0x800100}
Same for *link_text_start and -Ttext.
Ok for trunk and backport?

[*link_data_start]: Wrap -Tdata into %{!Tdata:...}.
[*link_text_start]: Wrap -Ttext into %{!Ttext:...}.
