Typically, the dfu_alt_info_* is defined in .h files as preprocessor macros with 'alt' info separated by semicolon. But when dfu_alt_info_* is added in the environment files(.env) the script at "scripts/env2string.awk" converts a newline to space. Thus adding a space character after semicolon. This results in incorrect parsing in dfu.c which is based on the information that 'alt' info are only semicolon separated. One option is to add dfu_alt_info_* variable in .env in single line. But there is possiblity for it to exceed the line length limit. So update the parsing logic to remove leading space characters before adding to the dfu list.
