Build C compiler errors when building from source on RHEL v8.9

[hhue13]

Due to issues running switcher 0.8.1 om REL8 (see issue 104 I tried to build it from source using the 0.8.1 source package. The OS I'm running is RedHat Enterprise Linux 8.9 on x86_64.

x@y: /dev/shm/kubeswitch-0.8.1$ uname -a
Linux x.a.b 4.18.0-513.9.1.el8_9.x86_64 #1 SMP Thu Nov 16 10:29:04 EST 2023 x86_64 x86_64 x86_64 GNU/Linux

x@y: /dev/shm/kubeswitch-0.8.1$ cat /etc/redhat-release 
Red Hat Enterprise Linux release 8.9 (Ootpa)

However when running the make all of the downloaded source package I'm running into issues with the C compiler invocation. No matter if I try to compile using clang or gcc.

Compiler versions I've tested with are: gcc

x@y: /dev/shm/kubeswitch-0.8.1$ gcc -v

The strange thing is however that the go binary is being built nevertheless as hack/switch/switcher_linux_amd64 and this still seems to work well - at least using local store.

So I'm wondering what's causing the compile error and what are the consequences of the failed compile (as the go binary is built anyhow).
