I'm familiar with autotools terminology and avoided using it explicitely
because I think the word "host" says nothing. This is why used
"build platform" (platform of the system where we build the software
using cross-tools) and
"target platform" (platform we build the software for).
If you think host/target is better I'm fine with it. No problem.

I think in most cases BUILD_DEPENDS are build host dependencies too.
I could not find cases where BUILD_DEPENDS is set manually in package's
Makefile and contains target-platform dependency.
bl3 is a pure target-platform only dependency.
If we stay with BUILD_DEPENDS as a list of host dependencies
and introduce TARGET_BUILD_DEPENDS
for bl3 (BUILDLINK_DEPMETHOD.xxx = build),
it will be easier to manually convert BUILD_DEPENDS to
TARGET_BUILD_DEPENDS in packages's Makefile when necessary.

They cannot. Otherwise our USE_TOOLS will have to support thousands of programs.
