I am running Arch ARM (aarch64) on an ODROID-C2 using gcc v8.2.1.
Arch ARM which ships with the following LDFLAGS as defaults,
"-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now"
When I build wireguard on this device as shown below, I get this error
but am unsure why:
ld: unrecognized option '-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now'
ld: use the --help option for usage information
make[2]: *** [scripts/Makefile.build:393:
/scratch/WireGuard-0.0.20190123/src/wireguard.o] Error 1
make[1]: *** [Makefile:1358:
_module_/scratch/WireGuard-0.0.20190123/src] Error 2
make: *** [Makefile:36: module] Error 2
If I remove the '-Wl' switch from the distro default, it builds
without error. Any advice is appreciated.

-Wl etc is not a valid linker flag, its a flag for gcc which passes the
following flags to the linker. so basicly the LDFLAGS are just wrong.
in general no CFLAGS or LDFLAGS should be overriden, since wireguard
uses exact he same flags which is used for compiling the kernel. so setting
custom flags should be avoided

Thank you for the reply. What is odd is that I can build just fine on
Arch x86_64 which uses the identical LDFLAGS. In any case, is your
recommendation to drop the -Wl portion of the LDFLAGS or so unset all
ie:
unset CPPFLAGS CFLAGS CXXFLAGS LDFLAGS DEBUG_CFLAGS DEBUG_CXXFLAGS

the kernel makefiles used for building on different architectures can be
very different. (see kernel sourcdir/arch/arm/Makefile or arch/x86/Makefile)
so some of them might also overwrite existing flags. what makes me
wonder. according to your build log you're setting various flags before
entering the wireguard dir and compiling.
why?

The Makefile you mentioned for this system would seem to be
/usr/lib/modules/3.16.62-1-ARCH/build/arch/arm64/Makefile
% grep FLAG /usr/lib/modules/3.16.62-1-ARCH/build/arch/arm64/Makefile

CPPFLAGS_vmlinux.lds = -DTEXT_OFFSET=$(TEXT_OFFSET)
OBJCOPYFLAGS :=-O binary -R .note -R .note.gnu.build-id -R .comment -S
GZFLAGS :=-9
LIBGCC := $(shell $(CC) $(KBUILD_CFLAGS) -print-libgcc-file-name)
KBUILD_CFLAGS += -mgeneral-regs-only
KBUILD_CFLAGS += $(call cc-option, -mpc-relative-literal-loads)
KBUILD_CPPFLAGS += -mbig-endian

CHECKFLAGS += -D__aarch64__
KBUILD_CFLAGS_MODULE += -mcmodel=large
KBUILD_CFLAGS_MODULE += $(call cc-option, -mpc-relative-literal-loads)
export TEXT_OFFSET GZFLAGS
I actually don't see a plain LDFLAGS in it... just LDFLAGS_vmlinux.

The packager on Arch (makepkg) has a config file (/etc/makepkg.conf)
that is read when a package is built by it which sets the build flags.
I just exported the flags therein on the shell then built manually to
keep it simple (ie without explaining about the packager). I can tell
you that I get the identical error when I build manually as shown or
with the packager.
Curiously, I only get this error when I build Wireguard on this
platform (again reading from /etc/makepkg.conf which sets those
flags). I can build anything else without the error (linux kernel,
ffmpeg, owncloud, nginx, etc.)

the problem here is that no external flags should be set for kernel
related builds. the kernel has its own flags
and exakt these flags must be used for wireguard and this is how it
works. otherwise strange things will happen.
but i also never used makepkg. a plain make / make install does the job
by itself
