[OE-core] [PATCH] mmc-utils: set the optimization to -O2

[Yue Tao]

From: Yue Tao <yue.tao at windriver.com>

The _FORTIFY_SOURCE > 0 must be used with optimization > 0, so force
the optimization 2.

The build error (_FORTIFY_SOURCE=2 with -O0)

"warning _FORTIFY_SOURCE requires compiling with optimization (-O)"
