Crosscompile Linux 3.15.3 for mips(el) vu solo2 Vlan module support (8021q)

i could already successfully crosscompile some binarys for mipsel vusolo2, ob ubuntu 14.04 32 bits with the toolchain mipsel-tuxbox-linux-gnu that i got from here http://shivanet.ro/tmp/mipsel-tuxbox-linux-gnu.tar.bz2. I did install copy the toolchain to the directory /opt/cross/mipsel-tuxbox-linux-gnu. Vusolo2 sat receiver runs linux 3.15.3 kernel, now i need vlan support (module 8021q). The idea ist to crosscompile the vlan module or the kernel if necessary and copy it to que box. What i did was download the sources for linux 3.15.3 then :

make ARCH=mips defconfig 
make ARCH=mips menuconfig

Selected vlan support (8021q) Then i issued the command with the path to my toolchain:

ARCH=mips CROSS_COMPILE=/opt/cross/mipsel-tuxbox-linux-gnu/bin/mipsel-tuxbox-linux-gnu-gcc  make all 

not certain if i have to select make all or make modules, my toolchain is not found.

What ist the right way to inform make where my toolchain is? I noticed that make is looking for mipsel-tuxbox-linux-gnu-gccgcc instead of mipsel-tuxbox-linux-gnu-gcc. Thanks in advance, kindly Vento
