Subject: linux-user: Move arch_parse_elf_property to aarch64/elfload.c
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8218eb6f52abd08c9e89baafdddec6f0d9234768;p=thirdparty%2Fqemu.git

linux-user: Move arch_parse_elf_property to aarch64/elfload.c

Rename the controlling macro to HAVE_ELF_GNU_PROPERTY to
match the other HAVE_* macros.
