toolchain/uClibc: Disable mips16 for uClibc for now
For now, build uclibc without -mips16. There's no mips16 syscall support AFAIK and uclibc uses inline assembly syscalls a lot. In addition, touching errno means touching a TLS model symbol, and that's not supported in gcc 4.6. The __set_errno macro can be put back to calling errno_location(). This allows much of the library to be built in mips16 mode. I don't understand the implications to the thread library of doing this. A list of "build as -mno-mips16" C source files can be placed in the mips architecture-dependent build files. Maintaining the list would be no fun.
