Avoid emitting asterisk in assembler section directives.

Several other places in lto-streamer-out.c take this same approach of simply
skipping a leading asterisk.  Bootstrapped and tests running now, will post to
-patches list when they finish.

Revision 155528 caused:

One error is

c_lto_20081222_0.wpa.o:(.text+0x7): undefined reference to `x'

The difference in o. files is

-  [ 4] .gnu.lto_*INT_x   PROGBITS        00000000 000040 0000e3 00      0   0

1

Either "*" is expected or the fix is incomplete.
