[PATCH/committed] sim: switch to AC_CHECK_FUNCS_ONCE & merge a little

[Mike Frysinger]

This avoids duplicate tests for functions between common m4, arches,
and any other sources that would trigger func tests.

Also manually delete known duplicate function tests between the m4,
bfin, and v850 ports.
