Subject: [PATCH 1/1] Silence uninitialized warning on ehdr_start_save
Older GCC, like 4.1/4.2, will issue an uninitialized warning on
ehdr_start_save. This patch silences by using
struct bfd_link_hash_entry ehdr_start_save = ehdr_start_save;
* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation):
Silence uninitialized warning on ehdr_start_save with older
GCC.
Upstream-Status: Backport
