Berkus Decker ce3b94e86e fix: 🐛 Fix 2/2 for objcopy unaligned sections bug 
This one restores rust-objcopy but explicitly aligns
the beginning of each section. This avoids incorrect
binary output (.rodata section was offset 10-12 bytes
because of unaligned section start).
 2023-07-29 04:08:18 +03:00
Berkus Decker d2ed7c21ac fix: 🐛 Fix 1/2 for objcopy unaligned sections bug 
Due to a bug in llvm-objcopy sections
must be explicitly aligned, see
https://github.com/llvm/llvm-project/issues/58407
and
https://github.com/rust-lang/rust/issues/102983

This fix just replaces rust-objcopy with a GNU
binutils counterpart from `brew install
aarch64-elf-binutils`. Next commit will do a
less intrusive fix.
