[meta-freescale] Qt base font and Qt5.7

[idealsim]

Hi i have build an image for an imx6 card with yocto Krogoth and meta Qt5  
master to have qt5.7 (especially for chart). To build the image i needed  
to remove qtbase-font from my conf to remove an error. But now when i  
deploy an app on the card i have this error :

QFontDatabase: Cannot find font directory /usr/lib/fonts.
Note that Qt no longer ships fonts. Deploy some (from  
http://dejavu-fonts.org for example) or switch to fontconfig.
EGL Error : Could not create the egl surface: error = 0x300b

If someone can help to resolve this issue ?

For information a build with qt5.6 work fine on the card !

Regards,

Mickaël
