[PATCH] size: Handle recursive ELF ar files.
- From: Mark Wielaard <mark at klomp dot org>

- Subject: [PATCH] size: Handle recursive ELF ar files.
eu-size didn't handle an ELF ar file that contained an ar file itself
correctly. handle_ar would recursively call itself but close the ELF
file before returning. Only close the ELF file at the top-level.
