In this article we compared different behavior of static, inline and static inline free functions in compiled binary.
All the following test was done under g++ 7.1.1 on Linux amd64, ELF64.
#pragma once
inline int only_inline() { return 42; }
static int only_static() { return 42; }

You might want to read this to get an introduction to armel vs armhf.
If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.
First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux
If there's no qemu-arm-static in the package list, install qemu-user-static instead
Use the following commands to compile and link the examples:
$ gcc -std=c17 -pedantic-errors -O0 -g -S sem.c
$ as --gstabs -o sem.o sem.s
$ gcc -o sem sem.o -lpthread
This implementation makes use of the C11 Atomic Operations Library.
