I noticed this problem as well. It seems to be caused by the fact that
DOWNLOAD_INNER passes $(1) and $(2) to the DOWNLOAD_WGET, which contain the
correct info, while it passes nothing to other downloaders, which have to
do on their own based on $($(PKG)_SOURCE). The latter is in turn undefined
for git (and other) methods, so it defaults to $(2)_BASE_NAME, which has the
"host-" prefix.

I had no time to go on and fix the issue properly.

Slightly off topic, I think we should consider having an extra argument to
GENTARGETS_INNER holding the lowercase package name, without the 
host-prefix,
as we do for the uppercase package name.
This would ease further operations and, ultimately, fixing the bug in 
discussion.

All of these are in my todo list (obviously unscheduled).
