iree: iree/hal/local/elf/elf_module_test failed to dispatch the simple_mul function correctly in RV32 config

Run https://github.com/google/iree/blob/main/iree/hal/local/elf/elf_module_test.cc resulting into a segfault in qemu-riscv32. The same code works fine in x86_64 and RV64 Linux configs

Broken at https://github.com/google/iree/blob/9b946d7ffaf08f7f6130e6aacb3692e53456eb45/iree

Steps to reproduce patch https://github.com/hcindyl/iree/commit/6fa9e8b9a65b34388d68183d3e360ef44c7625b6 and build the test

Additional context

• build the runtime with the RV32 baremetal results in the same segfault
• build and run the abs() iree bytecode module towards the vmvx target with the same RV32 Linux toolchain works fine

I will try to run the system emulator with the baremetal config later to see if I can gather more information than the segfault.
