Great to hear that!

Continuing on the subject: after moving away the complex folder the
compilation went a bit more, until this error appeared:

./arch/x86_64/syscall_arch.h:60: error: asm constraint 6 ('r') could
not be satisfied
make: *** [Makefile:159: obj/src/env/__init_tls.lo] Error 1

The file syscall_arch.h contains:
[...]
static __inline long __syscall6(long n, long a1, long a2, long a3,
long a4, long a5, long a6)
{
        unsigned long ret;
        register long r10 __asm__("r10") = a4;
        register long r8 __asm__("r8") = a5;
        register long r9 __asm__("r9") = a6;
        __asm__ __volatile__ ("syscall" : "=a"(ret) : "a"(n), "D"(a1), "S"(a2),
 /* line 60 here --->>>    */
"d"(a3), "r"(r10), "r"(r8), "r"(r9) : "rcx", "r11", "memory");
        return ret;
}

Well I don't know how to proceed now, I'm not familiar with the asm
macro, can I get some help?

I'm sorry I cannot give you a deeper investigation on this error.
