I'm getting undefined references to `___tls_get_addr' when trying to build
with this patch. However my ld has this symbol for sure...
$ nm /lib/ld-2.3.5.so | grep __tls_get_addr
0000dfc0 T ___tls_get_addr
0000d9d0 T __tls_get_addr
0000dfc0 t ___tls_get_addr_internal

perhaps it will compile on my machine then...
