[PATCH 14/15] ARM: do not use optimized do_div for ARMv3

[Arnd Bergmann]

The gcc-4.9 optimization goes wrong while building target_core_iblock.c
for ARMv3 and leaves a bogus reference to __aeabi_uldivmod in the
output:

ERROR: "__aeabi_uldivmod" [drivers/target/target_core_iblock.ko] undefined!

I could not find anyone who is interested in fixing it in gcc,
so as a workaround this disables the do_div magic, just like
we do for old compilers and for OABI.
