Honza,
I try to build this configuration:
../gcc-trunk/configure --prefix=/home/ed/gnu/arm-linux-gnueabihf-linux64

--with-arch=armv7-a --with-tune=cortex-a9 --with-fpu=vfpv3-d16 --with-float=hard
but make fails:

When I debug and set a breakpoint in varasm.c line 314 it looks as if
the flag SECTION_RELRO is different. This flag is set in
categorize_decl_for_section where it depends on
TREE_CODE(decl), and if it is a VAR_DECL also on
TREE_READONLY (decl)
TREE_SIDE_EFFECTS (decl)
DECL_INITIAL (decl)
TREE_CONSTANT (DECL_INITIAL (decl))
DECL_THREAD_LOCAL_P (decl)
maybe also on CONST_CAST_TREE (decl) in case of asan
and various target hooks.
now, since the error message names a ".localalias."
I see your checkin from monday at the same area:

* symtab.c (symtab_nonoverwritable_alias): Copy READONLY flag for
variables.
and I wonder if there are more flags missing:

This makes the build succeed for me, but I am not really sure, if that is
the right direction to fix this, and if maybe even more flags may be missing,
for instance: DECL_THREAD_LOCAL_P or CONST_CAST_TREE?
What do you think?
Bernd.
