[Patch, microblaze]: Port of Linux gdbserver

[Joel Brobecker]

[with my patch-champion hat]

I can't review the gdbserver Changes, but I can look at the rest.

Sorry Ajit. I should have seen this in the previous iteration, but
there are a couple more nits in the ChangeLog entry that you'll need
to fix.

First, gdb and gdb/gdbserver have distinct ChangeLog files, so you'll
need to have 2 ChangeLog entries if you touch both areas at the same
time.  This means that the filenames in gdbserver should not be
prefixed with "gdbserver/" in your ChangeLog entry.

Also, change "ChangeLog:" to "gdb/ChangeLog:" and
"gdbserver/ChangeLog:".

Please exclude the configure.host change. This looks unrelated.

There are indentation errors in the two hunks above. Use tabs.

It looks to me like you have many many trailing spaces in the file
you are submitting. Please strip them.

Some lines are too long, also.
