Ok.....it's been a week and I'm getting nowhere and need some help/direction.

Running Ubuntu 14.04 64bit, trying to build 64bit Motorola kernel. I believe my problem lies with the toolchain path? When I try to make the .config I get this:

aaron@ubuntu:~/kernel$ make ARCH=arm64 msm8994-perf_defconfig
arch/arm64/configs/msm8994-perf_defconfig:646:warning: override: reassigning to symbol HOB_SHARED_RAM
warning: (PCI_MSM && AMD_IOMMU) selects PCI_MSI which has unmet direct dependencies (PCI && ARCH_SUPPORTS_MSI)
warning: (ARCH_MSM) selects DEVFREQ_GOV_MSM_BW_HWMON which has unmet direct dependencies (PM_DEVFREQ && (ARCH_MSM_KRAIT || ARCH_MSM_BIMC_BWMON))
warning: (PCI_MSM && AMD_IOMMU) selects PCI_MSI which has unmet direct dependencies (PCI && ARCH_SUPPORTS_MSI)
warning: (ARCH_MSM) selects DEVFREQ_GOV_MSM_BW_HWMON which has unmet direct dependencies (PM_DEVFREQ && (ARCH_MSM_KRAIT || ARCH_MSM_BIMC_BWMON))
#
# configuration written to .config
#
aaron@ubuntu:~/kernel$

These are the warnings I don't know how to clean up, but thought since they were only WARNINGS, it would build. But when I make the menuconfig, it seems generic....or not what I expected from "Sabermod", pic at the bottom of the menu ui.

If I try to "make", I'm getting this:

aaron@ubuntu:~/kernel$ make -j2

This IS my first kernel rodeo, but I've been around for awhile. Usually very quick with this stuff, but I feel I'm missing/overlooking something really easy. Latest thing I tried to follow was THIS. Any help would be greatly appreciated. The only kernel for this device is an UBER one and it doesn't "feel" optimal. I want big teeth and claws, covered in graphite!
