[OE-core] intercept script "update_font_cache" failed, falling back to running postinstalls at first boot

[Yi Qingliang]

Hello,
	I'm building a readonly-rootfs, which contain ttf fonts wqy-zenhei, but 
fail with:

"
intercept script "update_font_cache" failed, falling back to running 
postinstalls at first boot
"

I found that:
http://lists.freedesktop.org/archives/fontconfig-bugs/2013-January/000452.html

it said that the fc-cache would have --sysroot option, maybe we can use it to 
avoid postintall?
