[Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

I see. You're right, the kernel is aarch64 but the compiler and build
tools are armhf. The chromium-browser build log reports the same, so
cross-compilation might not be necessary.

clang I can try to compile it in a armhf Ubuntu 16.04 .

According to this link (https://developer.mozilla.org/en-
US/docs/Mozilla/Developer_guide/Build_Instructions/Compiling_Firefox_With_Clang_On_Linux)
you just need to edit your mozconfig to set CC=clang and CXX=clang++. In
theory you could also test compiler flags like -mfpu=vfpv3-d16 just by
setting CFLAGS and CXXFLAGS.

Many thanks if you can try this out in your build environment.
