2b39d4f68b elfcopy: Avoid divide-by-0 on section alignment 0
According to ELF ABI, alignment 0 and 1 has the same meaning: the
section has no alignment constraints.

4a85c69160 Update elftoolchain to upstream rev 3136
This fixes two strip(1) issues found during ports exp-run and adds a
string hash implementation which significantly speeds up certain
operations on objects with large numbers of symbols.

This also improves libdwarf handling for stripped objects with
.eh_frame or .debug_frame (but not other debug) sections.

9ef62fdb87 Set up default shstrtab entries at shstrtab initialization
Instead of waiting until the addition of the first non-default entry.
This fixes a segfault when strip(1) is asked to remove every section from
an object file.

a356a1f51f Do not strip all when stripping an explicit symbol
When requested to strip specific symbols (-N flag) the default should be
to strip nothing (other than the requested symbols). This is consistent
with binutils strip(1).

30568ad37e Correct elftoolchain strip(1) memory size calculation
Calculate the segment's memory size (p_memsz) using the virtual
addresses, not the file offsets. Otherwise padding preceeding SHT_NOBITS
sections may be excluded from the calculation, resulting in a segment
that is too small.
