We'd like to learn how you solved your problems compiling ICU and why it
didn't compile in-tree :)
Btw, on current master and 3-6 we switched to ICU 49, maybe that solves
your problem already?

This sounds actually like a mix of --with-system-icu but without icu
being a system library, i.e. not registered with ldconfig. Quite
a corner case I'd say..

Despite that, for your scenario those places would indeed have to
augment and extend LD_LIBRARY_PATH instead of replacing it.

Detection source is in configure.in ICU* variables, icu-config is used
there to obtain the system's path. The gencoll_rule calls during build
you mentioned are emitted through gb_Helper_execute somewhere in
solenv/gbuild/*, it's the $(call gb_Helper_execute,gencoll_rule) in
i18npool/CustomTarget_collator.mk
