So I found the issue (it was a PIBKAC issue :/) I was using sudo to try and build the kernel (this was due to a messed up setup where the whole kernel src tree ended up being written by root). When copy-pasting my command here, I missed copying the sudo part and that was precisely the reason for the error. When invoking sudo, I think the current shells environment variables are not copied (probably due to security reasons) and that's why it was not picking up the toolchain paths. Once I fixed the permissions on the source tree and invoke make as regular user, it started working. Sorry about the noise, I should've figured this out earlier.

Hi All,
I'm having trouble compiling my kernel using a 32-bit toolchain (for ARM) on a 64-bit host (Ubuntu 14.10). The kernel version is 3.14.17.
I understand that 32-bit binaries require "ia32-libs" (or equivalent) for compiling on 64-bit hosts. I installed the required packages (lib32z1 lib32ncurses5 lib32bz2-1.0 for Ubuntu 14.10), but still keep getting errors:
$ make CROSS_COMPILE=arm-none-linux-gnueabi- all Makefile:616: Cannot use CONFIG_CC_STACKPROTECTOR_REGULAR: -fstack-protector not supported by compiler make: arm-none-linux-gnueabi-gcc: Command not found
Have built this toolchain or just downloaded from coudesourcery ? Go to the source where you downloaded toolchain (on your machine not the website) traverse to bin directory and try ./arm-none-linux-gnueabi-gcc --version.
