So firefox build with xenial toolchain have one more crash , mostly
because of different build enviroment from trusty to xenial .

So a solution will be to build firefox with trusty toolchain .

About the cross compile set up , I was happy but to early , it compile fine for 
30 minutes then stop compilation because a bug in rustc compiler . 
I most used 
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Cross-compiling_Mozilla
  and set up a xenial chroot . I installed some packages for xenial some for 
armhf . I uset rustup to install rust that can make target armhf .
But at one point I think it mix the include headers of x86 with the ones from 
arm .

I think the best is liek you said to set up a arm machine running ubuntu
trusty and use that to compile all . I think that way will work . Using
arm xenial just give one (or more ) crash not just the skia one .

Title:
  Firefox crashes at start on armv7L after 55.0.1 update

Status in Mozilla Firefox:
  Expired
Status in firefox package in Ubuntu:
  Confirmed

Bug description:
  Firefox always crashes when launched after the 55.0.1 update on an
  Orange Pi PC Plus (a single-board computer similar to a Raspberry Pi),
  even in safe mode.

  I did a fresh install of Armbian (a Ubuntu Xenial 16.04 re-spin for
  ARM single-board computer) on a similar board (Orange Pi Plus 2e),
  installed Firefox and experienced the same problem--it won't load
  without crashing.
