```
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?
