make.defaults: negative incrementals in USE_EXPAND (530222)
Previously, USE_EXPAND variable settings in profile make.defaults only
supported positive incremental settings. This patch adds support for
negative settings like PYTHON_TARGETS="-python3_3", which brings
behavior into alignment with PMS.
Notably, this patch does not change behavior for settings in make.conf.
In make.conf, settings to USE_EXPAND variables remain entirely
non-incremental. PMS does not govern make.conf behavior.
