Print the addresses of non-absolute symbols relative to _text

because kallsyms includes static symbols that are not exported
from their object files.

for (i = 0; i < table_cnt; i++) {
- printf("\tPTR\t%#llx\n", table[i].addr);
+ if (toupper(table[i].sym[0]) != 'A') {
+ printf("\tPTR\t_text + %#llx\n",
+ table[i].addr - _text);
+ } else {
+ printf("\tPTR\t%#llx\n", table[i].addr);
+ }

Doesn't this break kallsyms for almost everyone?

kallsyms addresses aren't used just for displaying, but also to find symbols from their addresses (from the stack trace, etc.).

Am I missing something?
