Stupid MSVC: bad C4706: assignment within conditional expression
...
- for (unsigned j=0; (k = dt_names[j]); ++j) {
+ for (unsigned j=0; ((k = dt_names[j]), k); ++j) {
The complaint was:
p_lx_elf.cpp(5710) : warning C4706: assignment within conditional expression
which is INCORRECT, as shown in the change which is 100% equivalent.
The assignment occurs BEFORE the conditional expression.

Bug in handling DT_GNU_HASH table.

Fix includes a more-general and stronger heuristic to find the end of
GNU_HASH table when there is no ElfXX_Shdr for it. 64-bit only for now.
