c924c32d54 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.

c36977f0b1 ELF: amd64-linux main programs use 2-step de-compressor 
The first $ARCH to move to 2-step de-compressor for ELF main programs.
De-compressor uses memfd_create to comply with strictest SELinux
settings (no PROT_WRITE on any PROT_EXEC page).
First step de-compressor always uses NRV2B to de-compress the second step,
and the second step can use a different de-compressor for each PT_LOAD.

08a38af553 Workaround bug in Alpine Linux 
"empty" DT_GNU_HASH lacked hasharr[0] when n_bucket==1,
which upx correctly detected as malformed.
