Subject: [PATCH] LoongArch: Modify inconsistent behavior of ld with
 --unresolved-symbols=ignore-all

Remove duplicated check when producing executable files that reference external symbols
defined in other files. RELOC_FOR_GLOBAL_SYMBOL will check it.

Testcase is:
resolv.c:
int main(int argc, char *argv[]) {
    return argc;
}

t.c:

extern const struct my_struct ms1;
static const struct my_struct *ms = &ms1;

t.h:
typedef struct my_struct {
    char *str;
    int i;
} my_struct;

Compiling and linking command with:
gcc t.c -c ; gcc resolv.c -c
gcc resolv.o t.o -o resolv -Wl,--unresolved-symbols=ignore-all

Got error as:
~/install/usr/bin/ld: t.o:(.data.rel+0x0): undefined reference to `ms1'
collect2: error: ld returned 1 exit status
