More work on GNU as generation
On _gas_mapping, label definitions do not allow "::". ":" must be
used instead.
gasOutput is now part of "options".
Unneeded sections, such as HOME/GSINIT/etc., are no longer declared
and/or defined. GNU as just does not need them.
Startup function name must equal "_start" for GNU ld.
The value of some macros, such as CODE_NAME or DATA_NAME, must change
according to options.gasOutput, as "CODE" or "DATA" (among many others)
are not understood by GNU as.
STM8 port now selects GNU as format on --gas switch enabled.
