Собираю тут qemu. Сталкнулся с text relocations. Упрощённый testcase:
kas@dhcppc0:pts/2 ~/tmp $ cat 1.c
int main() {
static __thread int i = 0;
i++;
return 0;
}
kas@dhcppc0:pts/2 ~/tmp $ gcc -fpie -pie 1.c
/usr/bin/ld: warning: creating a DT_TEXTREL in a shared object.
Есть идеи как это исправить и вообще откуда ноги ростут?

Ian Lance Taylor thinks that it's a linker bug, see thread starting at
http://gcc.gnu.org/ml/gcc-help/2009-07/msg00348.html
Looks like this bug is already fixed upstream:
http://sourceware.org/bugzilla/show_bug.cgi?id=6443
