I'm afraid -fmudflap won't work alone (might be easy to fix in gcc?):
    // a.c:
    int main() { return 0; }
$ gcc -fmudflap a.c -o a
    /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.6/../../../../lib64/crt1.o: In function `_start':
    (.text+0x20): undefined reference to `__wrap_main'
    /tmp/ccCbbGQy.o: In function `global constructors keyed to 00099_0_main':
    a.c:(.text+0x10): undefined reference to `__mf_init'
    collect2: ld returned 1 exit status
$gcc -fmudflap -lmudflap a.c -o a
    # all ok

same is true for all -{f,l}mudflap{,th,ir}
