    testsuite/52641 - Make analyzer tests pass (or skip) on AVR.

    This patch fixes some test cases that failed due to sloppyness,
    like:

       typedef unsigned int u32;

    instead of:

       typedef __UINT32_TYPE__ u32;

    On avr, many test failed to produce expected warnings since
    strcmp etc. is implemented as asm in a gnu inline wrapper.
