This patch changes the load_library() function in the dynamic linker to avoid reserving a huge read-only address-space range just to read the ELF header and program header (which are typically very small and easily fit in the first page). Instead, we use the functions in linker_phdr.c to only load the data that we need in a temporary mmap-allocated page of memory, which we release when the function exits. This avoids issues when loading very large libraries, or simply debug versions that only need to load a tiny percentage of their overall file content in RAM.
