ELF2: fix lzma on amd64-linux.elf-*
...
New -DWINDOWS_BACK so that amd64-win64.pe.h does not change.
This hides a real bug (unchecked), but would change anti-virus status.

Find+fix steps that were performed:
1. Find all 'add' instructions that compute "eof".
NRV run-time decompressors ignore srclen, so 'add' can be ignored for them.
$ cd upx-devel4/src/stub
$ grep -sr 'add.*eof' src | grep -v 'nrv2._d.*.S' | sort

On amd64, otool and lldb accept the results.
The entry point points to the unfilter and uncompress routines.
Somehow _start has been lost.
