[llvm-debuginfo-analyzer] Invalid logical view with (--print=sizes) on 'arm' and '32-bit multilib on amd64'

[CarlosAlbertoEnciso]

The 08-elf-reader patch for llvm-debuginfo-analyzer landed in:
https://reviews.llvm.org/rG4f06d46f465c8239ed0863abdd78f7ee1fbb42b4
https://reviews.llvm.org/D125783#3898878

The test case:
https://github.com/llvm/llvm-project/blob/main/llvm/test/tools/llvm-debuginfo-analyzer/DWARF/06-dwarf-full-logical-view.test
produces an invalid ouput as reported in:

The same problem reported building 32-bit multilib on amd64

This is also broken on i386 (so perhaps on all 32-bit platforms?):

From @mgorny:

But I can also reproduce in my working copy that's configured as:

CC=i686-pc-linux-gnu-gcc CXX=i686-pc-linux-gnu-g++ cmake ../llvm -G Ninja -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=MinSizeRel -DLLVM_TARGETS_TO_BUILD=X86 -DCLANG_ENABLE_ARCMT=OFF -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_CCACHE_BUILD=ON -DLLVM_ENABLE_PROJECTS='llvm' -DLLVM_BUILD_TESTS=OFF -DLLVM_HOST_TRIPLE=i686-pc-linux-gnu

where i686-pc-linux-gnu-* wrappers simply call the respective GCC executables with -m32
