Richard Purdie - April 24, 2014, 9:19 a.m.
Rather than building the whole of libgcc to obtain the unwind.h header
file, simply configure it and then install the file. This avoids copying
chunks of data around when we don't need to and building the same thing
twice.

After doing this we need to make sure the target build directory exists
in the libgcc case since it will no longer be created automatically.

if 0051-fix-unwind-race.patch is not needed then please delete it from
metadata as well. Ideally this should have been squashed with commit
d3b02218dcfedda8e4efb43b8fa6d13af8d91f78 before push
