x86: Clear extern_protected_data for GNU_PROPERTY_NO_COPY_ON_PROTECTED
When GNU_PROPERTY_NO_COPY_ON_PROTECTED is set, it indicates that there
are no copy relocations against protected data symbols. When linker
sees GNU_PROPERTY_NO_COPY_ON_PROTECTED on any input relocatable file,
it sets extern_protected_data to FALSE.
bfd/
* elf32-i386.c (elf_i386_link_setup_gnu_properties): Set
extern_protected_data to FALSE if GNU_PROPERTY_NO_COPY_ON_PROTECTED
is set on any input relocatable file.
* elf64-x86-64.c (elf_x86_64_link_setup_gnu_properties): Likewise.
ld/
* testsuite/ld-i386/i386.exp: Run protected7.
* testsuite/ld-i386/protected7.d: New file.
* testsuite/ld-i386/protected7.s: Likewise.
* testsuite/ld-x86-64/protected8.d: Likewise.
* testsuite/ld-x86-64/protected8.s: Likewise.
* testsuite/ld-x86-64/x86-64.exp: Run protected8.
