It's working fine with 4.3, native compiling static binaries under musl
and everything:

(sh4:3) / $ gcc /usr/src/thread-hello2.c -lpthread --static
(sh4:3) / $ ./a.out
Hello world!
(sh4:3) / $ cat /proc/version
Linux version 4.3.0 (landley@halfbrick) (gcc version 4.2.1) #1 Mon Jan
11 13:24:23 CST 2016
(sh4:3) / $ cat /proc/cpuinfo
machine		: RTS7751R2D
processor	: 0
cpu family	: sh4
cpu type	: SH7751R
cut		: unknown
cpu flags	: fpu ptea
cache type	: split (harvard)
icache size	:  4KiB (2-way)
dcache size	:  4KiB (2-way)
address sizes	: 29 bits physical
bogomips	: 120.00
(sh4:3) / $

(Dynamic linked binaries are segfaulting but that's something I did
wrong when switching to musl. My toolchain is the last gplv2 releases of
everything, patched until they work. Something needs a patch, apparently.)

I might cut a release with _just_ the new kernel version to catch up...
