The ebl_section_strip_p function used the Ehdr e_shstrndx field to get at the name of the (debug) sections. This is not correct if there are more than SHN_LORESERVE sections. Use elf_getshdrstrndx to get at the shstrtab section. And drop the Ehdr argument that isn't necessary anymore. Signed-off-by: Mark Wielaard <mark@klomp.org>
