JDK-8284997 - arm32 build crashes since JDK-8283326
Description
JDK-8283326 reworked the SafeFetch implementation and, on most platforms, switched to static assembly. 

On arm (32-bit), this change led to strange crashes (JDK-8284997). These problems are time consuming to analyze (among other things they only occur when building natively on a Rasberry Pi with one particular Docker setup). 

As a temporary workaround I'd like to switch SafeFetch to the sigjmp method for arm, until I find time to analyze these problems in more detail.
