Merge "Remove leading whitespace from dump-variables-rbc results"

# likely to be relevant to the product or board configuration.

# Soong config variables are dumped as $(call soong_config_set) calls

# instead of the raw variable values, because mk2rbc can't read the

# raw ones.

# raw ones. There is a final sed command on the output file to

# remove leading spaces because I couldn't figure out how to remove

# them in pure make code.
