The patch of mips32 compilation problem with native cross-toolcahin

File: packages/hal/mips/arch/current/src/redboot_linux_exec.c
Description: 

When compiling packages/hal/mips/arch/current/src/redboot_linux_exec.c will
lead error when using cross-gcc on pure Linux environment.

While if the compiler produced by chip vendor, like Atheros, or produced by
OpenWrt prject will encounter this problem. (gcc-4.4)

This is because function entry pointer "linux' is a predefined macro in native
gcc toolchain (as well as x86's toolchain).

The fix method is to replace this variable from "linux" to other name like
"linux_os".

Please refer to the attachment.
