Trying to guess how we were called does not work. Don't try to be smart, and take the full path, even if we are in PATH.

    10 

    11 On sh[34]-linux, memset function does not work if 2nd argument is negative

    12 and 3rd argument is greater than 12.

    13 for example, memset(ptr, "\xda", 20) sets 0xff instead of 0xda.

    14  

    15 Attached patch fixes this problem.

    16  

    17 	* sysdeps/sh/memset.S (memset): Correct 2nd argument handling.
