That is quite likely an unimplemented FPU opcode triggered by a call to udivsi in the libc.  Meaning:  you compiled with -ffast-math, hence the compiler will generate FPU opcodes whenever it sees it feasible and will not use any mathematics crutch like a software that emulates udivsi and friends and your system does not provide an FPU in hardware.
Solution: turn -ffast-math off by removing it and add -fslow-math.  Then keep your fingers crossed that the math functions needed are provided by libm against you should then link. If not, download an emulation code from a server of your choice and add that to your build.

Cheers,
    T.
