Strictly speaking, $(CC) or $(CXX) is used
when linking host programs.


See this.
https://github.com/torvalds/linux/blob/v4.17/scripts/Makefile.host#L95
https://github.com/torvalds/linux/blob/v4.17/scripts/Makefile.host#L112


In fact, there is no definition of 'HOSTLD' in the top Makefile.


I will reword it to:


HOSTLDFLAGS
--------------------------------------------------
Additional flags to be passed when linking host programs.


I will also move this hunk up
after LDFLAGS_MODULE.
