`in` operator in bjam always returns true if its first argument has no elements[1]. This means that if `os.platform` is empty (not detected), the construction introduced in commit9084161b87sets ABI to `aapcs` on all platforms where `os.platform` is empty, including, e.g. loongarch64, and breaks build there. This commit refactors the condition to use '=' operator, to make sure that when `os.platform` is empty we get the default ABI value, and thus fixes build on loongarch64. See also819c2d6423for similar fix that was somehow lost in refactorings. This time a comment is added near the condition in hope that future edits will not reintroduce the issue.
