Log:
Fix PR target/53440 - handle generic thunks better for TARGET_32BIT.


This partially fixes PR target/53440 atleast in ARM and
Thumb2 state. I haven't yet managed to get my head around
rewriting the Thumb1 support yet.

Tested on armhf with a bootstrap and regression test
with no regressions.

Queued for stage1 now as it isn't technically a regression.

Ramana
