Build error on ARM device due to ld flags

[John]

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.

Complete build log and my FLAGS:
