Almost all the symbols in config/sh/lib1funcs.asm are problematic.  
Moreover, adding a new function to lib1funcs.asm
can inadvertantly create a new exported symbol.  It is much safer to 
make the symbols by default not exported.

I'm currently working on merging most of the machine-dependent patches 
from our sources into gcc 4.1 - that's a 400 KB patch -
and this will change most of the FUNC definitions in lib1funcs.asm to 
HIDDEN_FUNC, and all the ALIAS defintions
into HIDDEN_ALIAS, and also change the way references to symbols in 
lib1funcs.asm are generated, so that for some
symbols GOT references are made rather than PLT ones when compiling 
pic/PIC code.
