Also it's already used within the Makefiles to override C-compiler, so
my patch won't change the current situation.

Unfortunately this DESTDIR trick won't work. Explicitly stated
variables from the Makefile itself have preference over the
environment variables unless they stated with "?=". At least this is
how GNU make works.
