[Tinyos-1.2wg] xscale tools

[Kristin Wright]

There are xscale libc rpms online to compliment the already existing
binutils and gcc rpms. Specifically:
http://www.tinyos.net/dist-1.2.0/tools/linux/xscale-elf-newlib-1.11.0tinyos-1.i386.rpm
http://www.tinyos.net/dist-1.2.0/tools/windows/xscale-elf-newlib-1.11.0tinyos-1.cygwin.i386.rpm

- Please take a look at what they include. I took out the info/* stuff
in the spec already, but can we perhaps trim some of the other
libc.a's? (There are thumb, internetwork, and be directories.) You can
get a listing of the files with this command:
rpm -q --filesbypkg -p xscale-elf-newlib-1.11.0tinyos-1.cygwin.i386.rpm

- To compile with the xscale 3.4.3 gcc that we have, I had to change
the code very slightly: there were some empty 'default:' clauses that
I added ';' to. That is, I changed 2 instances of  "default:" to
"default: ; ". Because the code is changed, albeit slightly, I
appended a 'tinyos' string to the version number.
