bug#6122: START_FILES is undefined on solaris2.10

[Lawrence Mitchell <wence@gmx.li>]

The recent changes to src/Makefile.in removed a conditional
definition of START_FILES.

|     Simplify STARTFILES definition.
|     * Makefile.in (STARTFILES): Remove conditional code, not needed anymore.

At least on solaris2.10, START_FILES is now undefined when
building, which causes make to fail because it doesn't know how
to build the STARTFILES target.

This fix to s/sol2-10.h allows Emacs to build successfully here,
although I am not sure if it is the correct one:

diff --git a/src/s/sol2-10.h b/src/s/sol2-10.h
index 865e175..d21bf85 100644
--- a/src/s/sol2-10.h

    (do not change this comment) */


I do not know if a similar fix should be applied in s/sol2-6.h or
s/usg5-4.h.

Cheers,

Lawrence
