This fixes a segfault when strip(1) is asked to remove every section from

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).

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.

The namesz and descsz variables need to be used in native endianness.
The sizes are in native order after swapping in the file to memory case,
and before swapping in the memory to file case.
This issue was identified for r273443, but the change was applied to the
wrong case. Revert r273443 to fix the to-memory case, and apply the
equivalent change to the to-file case.

the ELF file's byte order is not the native byte order. The
bug is that the variables holding the name and description size
are used (natively) after having been byte-swapped. The fix is
to calculate sz from them just prior to byte-swapping.
