[OE-core] [PATCH 1/1] directfb:filter out -fno-omit-frame-pointer option on x86 arch

[rongqing.li at windriver.com]

From: "Roy.Li" <rongqing.li at windriver.com>

directfb need -fomit-frame-pointer option of gcc to build some inline
asm code about mmx. But once -fno-omit-frame-pointer was added
into TARGET_CFLAGS. That will cause directfb build error on x86 arch.
