Bridgetest Failing on RPI4 armhf

[Luke Benes]

On Raspberry Pi OS with both gcc-8 and clang 12, the build is failing with the following error:

### float does not match! failed
struct comparison test failed
### float does not match! failed
recursive test results failed
standard test failed
exception occurred: error: test failed! /core/testtools/source/bridgetest/bridgetest.cxx:1175

> error: error: test failed! /core/testtools/source/bridgetest/bridgetest.cxx:1175
> dying...make[1]: *** [/core/testtools/CustomTarget_uno_test.mk:25: /core/workdir/CustomTarget/testtools/uno_test.done] Error 1

Stephan fixed a very similar issue for aarch64 here:
https://cgit.freedesktop.org/libreoffice/core/commit/?id=7b0ab85b4042cb38221ca5c9794b70c87443181f

Any ideas what's wrong here? Or how to get additional debug information?
