Hi

Got "Illegal instruction" while executing node.
From gdb trace, it shows fault at instruction

=> 0x36e24dd8: movw r7, #53100 ; 0xcf6c

root@OpenWrt:~/sandbox# cat test.js
console.log("hello world!");
root@OpenWrt:~/sandbox# node test.js
Illegal instruction

Tested with Raspbian Stretch and node.js official node-v6.11.2-linux-armv6l, it worked normally. There may be problems from OpenWrt something.

Raspbian:

#define __ARM_ARCH 6

#define __ARM_ARCH_ISA_ARM 1
#define __ARM_ARCH_5T__ 1

Probably we can fix this.

@godunkchen
The package has been updated.
Is the problem solved?

@nxhack
Sorry for late.
I've just verified it from upgrading node to version v8.11.3-1, it works fine now.

Great thanks for your contribution.
