A patch for hppa1.1-hp-hpux10.20 w/ --enable-shared

[Teemu Torma <tot@trema.com>]

I seems that libgcc should not be linked into shared libraries
on hpux10.20, or almost all eh-tests will fail.  I guess the same is
true for the other hpux versions.  With this patch, there are no
unexpected failures in check-g++.
