This patch shouldn't be necessary: you can give variable assignments
as arguments on the command line, and they should override basic
assignment within the makefile. See:
But it still makes sense, since overriding them is possible only when
passing the variable assignment as parameter to make, not via
environment variable.
Take this sample Makefile:
| foo1 = bar
| foo2 ?= bar
|
| all:
| @echo ${foo1} ${foo2}
Then look at the changing output:
| $ make foo1=foo foo2=foo
| foo foo
| $ foo1=foo foo2=foo make
| bar foo
Although it may be possible to overwrite the variables when calling
make, there certainly are build systems passing make variables via
environment.
