fs/binfmt_elf_fdpic.c: fix brk area overlap with stack on NOMMU
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/fs/binfmt_elf_fdpic.c?id=4ac313111018cb44ecc250445de5ccb93026a980
+ Loading static PIE ELFs on noMMU is possible since the linux kernel commit
+ 1bde925d2354 ("fs/binfmt_elf_fdpic.c: provide NOMMU loader for regular ELF binaries")
+ and it is subject to the same brk restriction.
