Subject: [PATCH] Update prvYieldCore() compile warning for single core targets
 (#505)

When configNUM_CORES is 1, prvYieldCore() generates an array subscript
outofbound error (-Warray-bounds) when compiled with GCC with space
optimization enabled (-Os).

This commit updates the code flow in prvYieldCore() to compile out
the part where yield is needed on the other core which is unnecessary
for single-core targets.
