commit 5d60ba7b05018cffc1de9330687d77870173747e
Author: pcpa <address@hidden>

    Minor updates when testing on a prototype, quadcore Loongson mips.
    
        * check/float.tst: Comment out the int to negative infinity
        test in mips for the moment because not all Loongson agrees
        on the result.
    
        * lib/jit_disasm.c: Add a test instead of an assertion
        when loading symbols for disassembly due to a failure with
        a simple binutils build in Debian mipsel64.
