[Buildroot] How to cross compile a shred object for arm

[Hmidi Slim]

Hello,
I have created a node module but when I run:
file my_module.node
I got this message:
ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically
linked, BuildID[sha1]=0xbf11cf557851a13e6c1d92651477ce65df0376b0, not
stripped
So,how can I cross compile it for ARM architecture??
Thanks
