ld/PE: don't emit relocations for weak absolute symbols

Browse Source 
First we should check the flag alone, not the entire flags value
matching BSF_WEAK. And then using "else if()" is inappropriate here: A
weak symbol can very well also be absolute, and hence wouldn't want a
relocation emitted despite being defined.
