imx-vpu (3.10.9-1.0.0): Fix build system to use OE build flags

happen and fix builds in O.S. Systems autobuilder.

+Organization: O.S. Systems Software LTDA.

+This is need to allow proper building when using Yocto and multiple
+machines sharing sstate-cache, otherwise the toolchain is going to
+default to use the first build machine sysroot due lack of '-sysroot'
+option.
