Disable EFI in the kernel and use normal stdenv

Browse Source 
In order to build the kernel without compressed instructions we need to
disable EFI support. We also need to leave the kernel to figure the
proper -march and -mabi flags, as otherwise it fails to build. Using the
option "CONFIG_RISCV_ISA_C n" disables the use of compressed
instructions.
