[Buildroot] [PATCH 1/1] openocd bump to 0.8.0

[Claudio Laurita <claudio.laurita@integrazionetotale.it>]

This is my first tentative of "real" collaboration, so thank you for the 
patience.

Ok, I thought it was not a lot ;-)

Ok. I thought it was inherited from the main patch. Silly thought.

You're perfectly right, obviously. I made an hard shortcut ;-)
I tried to find a way to avoid duplicating the logic of selecting 
options and finding related real dependencies. In current version it's 
not allowed any choice for the host and I think it's a limit. 
Duplicating everything is a bit redundant, but my idea was terribly 
based on my actual needs. I apologize.

This is a problem.
If I understand, changing this variable would affect every successive 
step of the global build. Is this the point? Not bad, as a mistake. I 
should have studied better the main makefile. Sorry.
Anyway, SHARED_STATIC_LIBS_OPT is added by default to the configure 
parameters. If your default is having shared preferred, It ends up in a 
first assignment to --enable-shared (the global) and a second one to 
--disable-shared (the local). Unfortunately, jimtcl ignores the second 
one and keeps building only the shared lib, making openocd build fail. 
The current BR implementation applies a patch to auto.def of jimtcl to 
force it ignore -enable-shared. I don't like much this approach and 
tried to find an alternative to avoid the patch. So, the only way is 
redefining OPENOCD_CONFIGURE_CMDS entirely?

Thank you very much for your attention.
