ARM segfault in sysimg generation

after commit 7c1140f ,build on ARM fail:

precompile.jl

after revert this commit ui/repl.c , build on ARM on trunk (412918a) is OK, may be we can use ifdef to solve this problem?

On my system we are asserting out while compiling Base._atexit.
backtrace

The REPL still does start though, even after the build bails out. It looks like we might be using the wrong ABI in imaging mode (I get the "ccall is using the llvm ABI" warning message while building, as expected).

thanks. i'll push a fix shortly

I experimented with doing a screen-capture while debugging / fixing this. if anyone's bored enough to listen to me rambling for an hour, it's now available at https://youtu.be/oX0Hl5FL7IM.

@vtjnash So somehow you didn't hit #12082 ?

[vtjnash]

I did, but thought it was an unrelated bug since the same fix was working on x86_64

[yuyichao]

I see. (Apparently I'm only 5min into the video ....)

[torrange]

Cheers Jameson - I will endeavour to listen to your ramblings! ;)

@vtjnash Can we have a 24/7 livecam?

[torrange]

Haha. So, there is a market for that. Albeit a niche one, I'm sure.
