* QA Notice: The following files contain runtime text relocations
 *  Text relocations force the dynamic linker to perform extra
 *  work at startup, waste system resources, and may pose a security
 *  risk.  On some architectures, the code may not even function
 *  properly, if at all.
 *  For more information, see:

I looked into it a bit, it seems they added a lazy load generator that generates .asm files with 32-bit non-PIC code like this:

___LazyLoad___XChangeProperty:
%ifdef RT_ARCH_AMD64
    lea     rax, [g_szXChangeProperty wrt rip]
    lea     r10, [NAME(g_pfnXChangeProperty) wrt rip]
    call    LazyLoadResolver
%elifdef RT_ARCH_X86
    push    g_szXChangeProperty
    push    NAME(g_pfnXChangeProperty)
    call    LazyLoadResolver
    add     esp, 8h
%else
 %error "Unsupported architecture"
%endif
    jmp     NAME(XChangeProperty)

I am not inclined to fix this, it is only on x86.  Patches welcome.
