52400e2561 /proc/self/exe now is optional 
... for the benefit of 'unshare', 'chroot', etc.
If not present, then upx run-time stub unmaps all pages of original main program.

067895fa5f Fix brk+munmap in folded stubs for main programs 
qemu emulating a compressed ET_EXEC revealed an access to ElfXX_Phdr
on the discarded side of brk() during cleanup. qemu was more aggressive
than the Linux kernel implementation of brk().

9e8de4abe5 i386: new stub strategy to avoid problems with early mmap layout 
The stub occupies the same region that execve() would create
for the original progam.  The stub copies everything to a new area,
erases the original region, replaces it with the de-compressed
program, and erases the copy of itself via the escape hatch.
The copy is inexpensive via mmap() of /proc/self/exe.

c4a921283a Revamp powerpc{,64le,64}. 
Fix 64-bit stack frame (8*8 bytes for spilling a0-a7).  Avoid using r2 (t0).
Prepare for -pie executables.  Prepare for unified strategy in stubs.

5de83a606e Cleanup after Thierry Fauck changes for ppc64le. 
We need a "UPX standard" compiler in order to re-compile the stubs for ppc64le;
meanwhile use Thierry's "pre-compiled" stubs.
Revert powerpc stubs to those produced by UPX standard powerpc.405-linux-gcc-3.4.5.
Cleanup the workarounds that Thierry used because he lacked upx-stubtools 20130920.
ARMv8 (64-bit) compiles but is incomplete and does not run yet.
