[PATCH, GCC, stage4] Fix type for .init_array.* and .fini_array.* sections

[Thomas Preudhomme]

Hi,

Several tests started failing for ARM targets (eg. gcc.dg/initpri1.c)
after change 6f9dbcd42f2cf034a9a21f46842c08d2e88449db in binutils. This
is because the non-default priority init_array and fini_array sections
are not created with NOTYPE flag as is the case for default priority
init_array and fini_array sections (see default_section_type_flags in
varasm.c for instance). This patch fixes the issue.

ChangeLog entry is as follows:

*** gcc/ChangeLog ***

2017-04-11  Thomas Preud'homme  <thomas.preudho...@arm.com>

        * config/arm/arm.c (arm_elf_asm_cdtor): Create non-default
        priority .init_array and .fini_array section with SECTION_NOTYPE
        flag.

Testing: with this patch test gcc.dg/initpri1.c succeeds but fails
without.

Is this ok for stage4?

Best regards,

Thomas
