Update pefile.cpp
...
I found a bug by participating to the Binary Golf Grand Prix 3 (https://tmpout.sh/bggp/3/ ) : upx text.exe segfaults when NumberOfSections in the IMAGE_FILE_HEADER is NULL, so
if (memcmp(isection[0].name,"UPX",3) == 0) triggers a NULL pointer dereference causing a crash.
To fix it, just have to check if isection is NULL (which means NumberOfSections = 0) or not.

Stupid MSVC: bad C4706: assignment within conditional expression
...
- for (unsigned j=0; (k = dt_names[j]); ++j) {
+ for (unsigned j=0; ((k = dt_names[j]), k); ++j) {
The complaint was:
p_lx_elf.cpp(5710) : warning C4706: assignment within conditional expression
which is INCORRECT, as shown in the change which is 100% equivalent.
The assignment occurs BEFORE the conditional expression.

WIP: smallest executable on Apple M1 (aarch64 or arm64)
...
Requirements for success after snipping a loader_command:
"codesign -s - my_app" must succeed.
"lldb my_app; process launch -s; continue" must succeed.
Optional loader_commands (macho-snip can remove these successfully):
LC_UUID, LC_BUILD_VERSION, LC_SOURCE_VERISON,
LC_DATA_IN_CODE (when 0==datasize)
Apple "strip -N" clears out LC_SYMTAB and LC_DYSYMTAB, but leaves
LC_DYLD_INFO_ONLY.export_size. Perhaps this could be zero if
constructed that way; snipping seems tedious because codesign
requires that __LINKEDIT must have no gaps.
LC_FUNCTION_STARTS seems to be required by codesign.
codesign wants offsets that point into __LINKEDIT to be in order:
LC_DYLD_INFO_ONLY, LC_FUNCTION_STARTS, LC_DATA_IN_CODE, LC_SYMTAB
MacOS seesm to require LC_LOAD_DYLINKER (else "zsh: Kiled"),
which seems to require LD_LOAD_DYLIB (else SIGABRT).
