Subject: [PATCH] Don't skip weak symbols during ar creation

```
$ echo 'int __attribute__((__weak__)) f(void) { return 4; }' > w.c
$ tcc -c w.c -o w.o

$ tcc-old -ar rc w.a w.o; nm -s w.a  # previous behaviour, not indexed
w.o:
0000000000000000 W f

$ ar rc w.a w.o; nm -s w.a           # GNU binutils behaviour, indexed
Archive index:
f in w.o

0000000000000000 W f

$ tcc-new rc w.a w.o; nm -s w.a      # new behaviour, indexed
Archive index:
f in w.o

0000000000000000 W f
