That may be what you WANT it to do, but that's not what it DOES.

Again, that may be what you want but that's not what your makefile says.
What this says:
> NORMAL_INSTALL = :
> @ HOST="$(HOST)" \
is create two make variables; the first line creates a make variable
"NORMAL_INSTALL" which is set to the value ":".
The second line creates another make variable "@ HOST" (in 3.81 and
below) which is set to the value '"$(HOST)" ...'. In newer versions of
GNU make this is an error, as I've said, because make variables with
whitespace in the name are no longer valid.

No. There is one such special character and it's backslash ("\").
