polarssl: replace BIGNUM_C_IMPLEMENTATION check

Browse Source 
Replace the BIGNUM_C_IMPLEMENTATION check by a check on POLARSSL_HAVE_ASM
and __arm__. This way it's possible to use this code on non arm, but
also to run the GNU/Linux emulation on an arm machine, which is useful
for debugging and profiling.
