(Only to port-sh3, because this is sh3 generic.)

This is a simplified (don't disturb irrelevant parts) version of
previous, plus converting all sh3 ports (dreamcast and mmeye were
missed).

Each port defines default TEXTADDR as DEFTEXTADDR.  If each kernel
config doesn't define TEXTADDR, DEFTEXTADDR is used.  This is what
other ports are doing. LINKFLAGS_NORMAL=-X is most ports are use too.

Tested only on COMPUTEXEVB (evbsh3).
