Modified Files:
        src/libexec/ld.elf_so: map_object.c

Log Message:
really unmap the gap between the text and data rather than just removing
all access with mprotect().  the latter results in the kernel having to
keep track of that range separately since the permissions are different.
avoid calling mmap() with a size of zero.
