[Bug ld/3197] New: ld --hash-style=gnu crashes

address@hidden hash]$ cat x.c
void
foo (void)
{
}
address@hidden hash]$ make
cc -fPIC   -c -o x.o x.c
./ld -shared --hash-style=gnu -o x x.o
make: *** [x] Floating point exception
make: *** Deleting file `x'

(gdb) r
The program being debugged has been started already.
Start it from the beginning? (y or n) y

Starting program: /export/home/hjl/bugs/binutils/hash/ld -shared
--hash-style=gnu -o x x.o

Program received signal SIGFPE, Arithmetic exception.
0x08091da7 in elf_link_output_extsym (h=0x9c95400, data=0xbfe70870)
    at /net/gnu-13/export/gnu/src/binutils-import/binutils/bfd/elflink.c:7078
7078          bucket = h->u.elf_hash_value % bucketcount;
(gdb)

The problem is that bucketcount is set when --hash-style=gnu is used. I will fix
it with a testcase.
