Illegal instrunction while running debootstrap

Hello,

I was trying to debootstrap Debian stretch on a MIPS machine, and 
apparently it fails with "Illegal instruction" error.

Would you please tell me what is missing in my proceessor? It's a
Mediatek MT7628ANN SoC, here goes cat /proc/cpuinfo output:

root@OpenWrt:/mnt/sda2# cat /proc/cpuinfo 
system type		: MediaTek MT7628AN ver:1 eco:2
machine			: TP-Link TL-MR3420 v5
processor		: 0
cpu model		: MIPS 24KEc V5.5
BogoMIPS		: 385.84
wait instruction	: yes
microsecond timers	: yes
tlb_entries		: 32
extra interrupt vector	: yes
hardware watchpoint	: yes, count: 4, address/irw mask: [0x0ffc, 0x0ffc, 0x0ffb, 0x0ffb]
isa			: mips1 mips2 mips32r1 mips32r2
ASEs implemented	: mips16 dsp
shadow register sets	: 1
kscratch registers	: 0
package			: 0
core			: 0
VCED exceptions		: not available
VCEI exceptions		: not available


I was trying both mips and mipsel release, but it seems like mipsel is
the correct one (at least ELF architecture ID is the same).  Is it
possible to run any Debian release on this machine?

Thanks in advance!
