And this reminds me of

    https://issues.dlang.org/show_bug.cgi?id=12268
    Issue 12268 - full static linking does not work, unresolved 
__tls_get_addr
    (2014)

    
http://forum.dlang.org/thread/vewesvrimtnmcrtygjam@forum.dlang.org
    dmd (v2.075.0): fully static linking: undefined reference to 
`__tls_get_addr'
    (2017)

I don't know if this is the right way to work around this issue:

    #define _GNU_SOURCE
    #include <dlfcn.h>

    __attribute__((force_align_arg_pointer)) void *__tls_get_addr 
(void *ti)
    {
       void *(*tga)(void*) = dlsym(RTLD_NEXT, "__tls_get_addr");
       if (! tga)
          return ti;
       return tga(ti);
    }
