libstdc++-v3 configuration and check problems under hpux 10.20

["John David Anglin" <dave at hiauly1 dot hia dot nrc dot ca>]

I noticed two issues with v3 under hpux 10.20:

1) There is a failure in the libtool CXX configuration regarding the ability
   of g++ to build shared libraries.  This should be possible although I
   know you need `-shared -fPIC' in the command.  Normally, the hardcode
   method is relink.  Puzzled why the command to parse nm output failed.

2) mkcheck fails with an error (see below).
