Some device tree files use the word 'linux' which gets replaced with '1' by many version of gcc, including version 4.7. So undefine this.
I think this is not a good way to address this issue. The GCC documentation (section "System-specific Predefined Macros" [1]) desribes how this should be handled. The "correct" (TM) way to fix this is by adding "-ansi" or any "-std" option that requests strict conformance to the compiler/preprocessor command line.

Stephen suggested a slightly more extreme version too - I was worried that all the typing stuff in U-Boot headers would break in this case, but I didn't actually test it, so perhaps it is fine.
