While compiling trunk on ARM with GCC 4.2 and enabling LDSO_GNU_HASH_SUPPORT I stumbled upon this problem.
GCC made a call to libgcc function __aeabi_uidivmod()->__div0()->__raise() and raise is not yet compiled in at the time of compiling ldso
so I got well known undefined symbol __raise problem

This patch uses the do_rem () macro to do the same operation.
