Consider the following Makefile:
   FOO += $(BAR)
   BAR := bar
   foo:
           @echo $(FOO)

FOO=foo make -f test.mk

outputs "foo bar" (while make -f test.mk FOO=foo output "foo")

pymake outputs "foo".

The real life case is that we export DLLFLAGS in security/build/Makefile.in, and security/coreconf/WIN32.mk appends -OUT="$@" to it. So the value ends up being whatever was exported + -OUT="", which fails to build.
