  • custom/pc386.cfg: make-exe rule would write into $(PROJECT_RELEASE) area. This is not cool because it $(PROJECT_RELEASE) is generally not writeable after the BSP is installed and you do not want every application installed there by default. Reported by Eric Norum <eric.norum@…>.

42#| top is of course another limit. Make sure there is enough space before the
43#| upper memory limits for the image and the memory allocated by it to fit.
