When compiling I am getting this error:

.....
  Building modules, stage 2.
  MODPOST 14 modules
ERROR: "abort" [lib/mpi/mpi.ko] undefined!
scripts/Makefile.modpost:92: recipe for target '__modpost' failed
make[6]: *** [__modpost] Error 1
Makefile:1215: recipe for target 'modules' failed
make[5]: *** [modules] Error 2
.......

This module has the abort symbol:
hauke at hauke-desktop:~/openwrt/lede$ nm
build_dir/target-arc_archs_uClibc/linux-archs38_generic/linux-4.14.14/lib/mpi/mpi.ko
|fgrep abort
         U abort
hauke at hauke-desktop:~/openwrt/lede$

This is my configuration:
hauke at hauke-desktop:~/openwrt/lede$ ./scripts/diffconfig.sh
CONFIG_TARGET_archs38=y
CONFIG_TARGET_archs38_generic=y
CONFIG_TARGET_archs38_generic_Default=y
CONFIG_PACKAGE_kmod-crypto-aead=y
CONFIG_PACKAGE_kmod-crypto-authenc=y
CONFIG_PACKAGE_kmod-crypto-hash=y
CONFIG_PACKAGE_kmod-crypto-hw-ccp=y
CONFIG_PACKAGE_kmod-crypto-manager=y
CONFIG_PACKAGE_kmod-crypto-null=y

CONFIG_PACKAGE_kmod-crypto-rsa=y
CONFIG_PACKAGE_kmod-crypto-sha1=y
CONFIG_PACKAGE_kmod-crypto-sha256=y
CONFIG_PACKAGE_kmod-random-core=y

I am also using your new toolchain based on gcc 7.1.

Does the arc CPU also need some special handling like some MIPS CPUs:

Is this patch still needed? Did you check if this problem still exists
with kernel 4.14?
