Make is horrible, here's how bits of the horror work:

Environment variables become the default values of make variables when
make starts, but there are two forms of assignment in make: ?= leaves a
variable alone if it already has a value, = overwrites unconditionally.
 Make developers tend to use the = without thinking about it.

To overcome this, variables assigned on the make command line become
read-only and cannot be overridden by make assignments.  (The
assignments are ignored.)  Thus you specify your architecture and cross
compiler on the command line, not in environment variables.

Then we get into recursive make, which is an abomination:


And really, the whole of make has outlived its usefulness, but I've
ranted about that here (at length) before:
