Hi all,

Recently, I upgrade my LEDE toolchain to binutils 2.28 & GCC 7, notice
I cannot SSH to router.

A more detailed description can be found
later, Kevin find it might related to libtommath

Two possible solution:

i. change libtommath compilation flag from -Os to -O2:

ii. update the bundled libtom* to latest:

Please update the bundled libraries to latest, or help to find the root cause.

Thanks in advance

Best Regards,
Syrone Wong
