It looks like a linker bug to me:
https://sourceware.org/bugzilla/show_bug.cgi?id=34165
[hjl@gnu-tgl-3 tmp]$ cat x.c
__attribute__((weak))
__attribute__((visibility("hidden")))
__attribute__((tls_model("initial-exec")))
extern __thread int x;
int
main (void)
{
return x > 30;
}
[hjl@gnu-tgl-3 tmp]$
/export/build/gnu/tools-build/glibc-many/install/compilers/alpha-linux-gnu/bin/alpha-glibc-linux-gnu-gcc
