From: Peter Maydell <peter.mayd...@linaro.org> A target_mmap() call in load_elf_binary() was missing the MAP_ANONYMOUS flag. (Spotted by Coverity, because target_mmap() will try to use -1 as the filedescriptor in this case.)
This has never been noticed because the code in question is for handling ancient SVr4 iBCS2 binaries.
