[v4,06/10] Add tdesc osabi and architecture functions
Commit Message
From: Alan Hayward <alan.hayward@arm.com>
Add functions to access to printable names for osabi and architecture in
target_desc.
I wanted to add these as member functions of target_desc, but cannot until
target_desc is moved into the header files.
Identical to V3 version.
Alan.
