Moving SPL_LDSCRIPT to Kconfig triggered an unfortunate attempt of command substitution, as the sourced auto.conf may include $(ARCH) which tries to execute a command 'ARCH'. This showed up as a warning similar to the following: include/config/auto.conf: line 209: ARCH: command not found This change does no longer attempt to source auto.conf, but rather passes it through awk to retrieve the values for CONFIG_LOCALVERSION and CONFIG_LOCALVERSION_AUTO. This will also mitigate the risk of unintended command substitution.
