[patch] PR 12983: Fix nm to decompress debug sections when printing line numbers

[Cary Coutant]

The nm tool doesn't currently request BFD to decompress input
sections, so when it tries to print line numbers we get an internal
error. This patch fixes that.

Is this OK for trunk? (I'd have called it obvious, but I wasn't sure
about the placement of the code to set the flag. The flag seems to
propagate to archive members, so it didn't seem necessary to set the
flag explicitly for each archive member.)
