I've checked the links you are referring: Both

* are related to webkit and from 2016
* deal with runtime errors not build errors as referred in patch description.

So what do you want to fix exactly?

commit 511a3764506ce6bbdc5e9441a8f4e9d862ea1102
Author: Andreas Müller <schnitzeltony@googlemail.com>
Date:   Mon Jan 4 11:04:16 2016 +0100

    qtscript/qtwebkit: disable thumb for armv4 and armv5 only to fix
segfault on armv7

Curently recipe has

ARM_INSTRUCTION_SET_armv4 = "arm"
ARM_INSTRUCTION_SET_armv5 = "arm"

Isn't thumb default any more?

Thumb-1 doesn't really work since it shows up with register allocation
errors with gcc.
thumb2 is fine for armv6+

Sorry for causing confusion - what I meant: Isn't thumb2 default for
armv7 anymore (particularly RasPI > 1).  If thumb2 is still default
for armv7 there is no need to add it explicitly here. It does not do
any harm but it is not necessary.

Distros are free to choose ISA so we really can not rely on the fact when
default tune was to use thumb 2 moreover it’s not default

Got it - but with a bit more love on patch description I wouldn't have
wasted your time:)

ARM_INSTRUCTION_SET isn't set to thumb in default config, so even with
thumb in TUNE_FEATURES it's not actually used anywhere in default config.
