The BRK_BUG value is used in the BUG and __BUG_ON inline macros. For
standard MIPS cores the code in the 'tne' instruction is 10-bits long.
In microMIPS, the 'tne' instruction is recoded and the code can only be
4-bits long. We change the value to 12 instead of 512 so that both
classic and microMIPS kernels build.
