Log:
- Emulate RDHWR instruction for TLS support
Reading register $29 with RDHWR is becoming the de-facto standard to
implement TLS. According to linux-mips wiki, MIPS Technologies has
reserved hardware register $29 for ABI use. Furthermore current GCC
makes the following assumptions:
- RDHWR is natively available or otherwise emulated by the kernel
- Register $29 holds the TLS pointer

Thanks for spotting it. Fixed.
