The mips74k subtarget of brcm47xx configures gcc to compile for mips32r2;
however, the generated kernel config for 3.14 and later kernels ends up
with CPU_MIPS32_R1 and CPU_MIPSR1 selected. The generated kernel config
for the 3.10 kernel (Barrier Breaker) properly selected CPU_MIPS32_R2 and
CPU_MIPSR2. Modify the default kernel config for mips74k to explicitly
select CPU_MIPS32_R2 and CPU_MIPSR2.

With this patch the mips74k subtarget will be compiled with optimized
compiler options to generated smaller and faster code. This currently
breaks broadcom-wl, because the binary blob is only compiled with
mipsr1 support.

All new devices (with MIPS 74K CPU) are based on BCMA SoC and have
Ethernet core supported by bgmac. Create a new subtarget to generate
optimized builds.
This is just a beginning, further tweaks (like kernel configuration)
are still possible. This decreases default root.squashfs by ~128 kB.
