Re: Add --enable-linker-verssion

Output sections without any input sections to initialise their flags
have their flags initialised by data statements to LOAD, ALLOC,
HAS_CONTENTS by default.  This is wrong for .comment.  Fix that by
making the script initialise the section type to INFO, one of the
noalloc section types.  That also allows the address of .comment to be
set to zero, as is usual for non-alloc sections.

Also, use source_sh for all of the sourced scripts to set up make
dependencies.
