s390x is big-endian which we currently don't support (#5111).

Only build on architectures supported by Debian. This excludes the
following little-endian architectures:
alpha arm ia64 riscv64 sh4 x32 arm64ilp32 mipsn32el
and the following big-endian ones:
avr32 hppa m68k mips mips64 mipsn32 powerpc ppc64 s390 sparc sparc64

fix(common/core/desktop): Fix warnings when compiling for armhf 🍒

(Fixes #5100)

(cherry picked from commit d91d27be)

Compiling on armhf outputs two warnings:
- NULL used in arithmetic [-Wpointer-arith] (line 289 and 290)
- unused parameter ‘dwFileSize’ [-Wunused-parameter] (line 264)

(related to #5072)

(cherry picked from commit 99e9a7cf)

Fixes #5095.

If the text editor was loaded, `SetText` would not be synchronous
because it executed some Javascript to make the text change, so setting
the text and immediately reading it again would give the old text. This
is what the On Screen Keyboard editor was doing (it would synchronize
the visual editor and text editor at save). This fix updates `SetText`
to update the backing store as well as the front end editor.

fix(web): position popups correctly in landscape mode on Android and during Chrome emulation 🍒

fix(developer): kmconvert commandline and deploy 🍒

A few fixes and improvements:
* kmconvert was missing a command line parameter for `-target` to
  specify the platform targets for a project
* kmconvert should avoid throwing unhandled exceptions, rather if
  sentry is not present then just write to console.
* Include kmconvert and its data files in the deployment of kmcomp.zip,
  which is done on the build agent (just need to make sure files are
  in the right place here.)
* Side fix: also made sure kmcomp would emit the exception message to
  console if sentry is not present.

fix(android/engine): Check lexical-model file exists before using 🍒
