```
const char * remote_n1 (void);

const char * call_remote_n1 (void) { return remote_n1 () + 1; }
```

with command : `-O1 -fPIC -mlong-calls` will generate `R_ARM_ABS32` relocation type for `remote_n1` ,
this lead to link error when create shared object : 

```
relocation R_ARM_ABS32 cannot be used against symbol 'remote_n1'; recompile with -fPIC
```

Source code do the assert check in DEBUG edition, but not warning in RELEASE edition

Besides, GCC work fine. 
Have SPEC about this rule?
