[PATCH] debugedit: Use ELF_F_PERMISSIVE when using ELF_F_LAYOUT

[Mark Wielaard]

Normally elf_update will do some strict checks on sections,
specifically it will check that sh_size is a multiple of sh_entsize
(if not zero).  This might prevent debugedit from writing out some
sections it just wants to keep unchanged (even if they aren't strictly
valid ELF).

	* tools/debugedit.c (fdopen_dso): Set elf_flagelf
	ELF_F_PERMISSIVE.
