Eduardo Habkost e916a6e88a oslib-posix: Print errors before aborting on qemu_alloc_stack() ... If QEMU is running on a system that's out of memory and mmap() fails, QEMU aborts with no error message at all, making it hard to debug the reason for the failure. Add perror() calls that will print error information before aborting.
