Welcome to MoarVM!

Configuring native build environment ...................
    trying to compile a simple C program ............... YES
    probing support of -Werror=* ....................... YES
    Testing pkgconfig .................................. 2.2.0
    probing stdatomic .................................. YES
Adding extra include for libffi: -I/usr/lib64/libffi/include
Defaulting to mimalloc because you have <stdatomic.h>
OK

    probing whether your compiler thinks that it is gcc  Can't compile simple gcc probe, so something is badly wrong at build/probe.pm line 208.
