rng-tools: Fix textrels on 32bit x86
When testing core-image-sato with hardening flags, it fails with
SIGSEGV in libc.so during relocation time
This is due to relocations in .text [textrel]
build QA points it out clearly during qemux86 build as well
AssertionError: 2 != 0 : Log: /mnt/a/oe/build/tmp/work/qemux86-bec-linux-musl/core-image-sato/1.0-r0/dmesg_output.log
