[PATCH-SH]:Generating proper relocations to link with Renesas SHC linker

[Asgari J. Jinia]

Hi,

If GNU object file for SH target which contains static functions is linked 
with other Renesas SHC objects by SHC linker, it does not call GNU 
functions properly. It always calls the first static function when other 
static functions are called. This is because GNU assembler does not emit 
relocations with addend values in case of static functions.

Following patch emits addend value in relocations for static declarations so 
that it will correctly link with Renesas linker.

Testcase:
Following is simple test code.
Command Line: sh-elf-gcc test.c -c -mhitachi -o test.o

/* test.c */
static int foo( int a, int b, int c)
{
	return a+b;
}
static int bar( int a, int b, int c)
{
	return a+b;
}

int dummymain()
{
	foo(1,2,3);
	bar(1,2,3);
}

If test.o is linked with Renesas SHC linker and called "dummymain", "foo" is 
called instead of "bar".
