[Bug driver/26876] New: Incorrect handling of -B by gfortran driver


The HP dynamic loader requires all symbols to be defined.  I've been
working on a revised method for handling weak undefined symbols introduced
by the crt*.o files.  Specifically, they need to be removed from shared
libraries such as libgcc_s.sl.  Moving the stubs into their own library
introduced many fails in the gfortran testsuite similar to the following:

Executing on host: /test/gnu/gcc-4.1/objdir/gcc/testsuite/../gfortran
-B/test/gn
u/gcc-4.1/objdir/gcc/testsuite/../
/test/gnu/gcc-4.1/gcc/gcc/testsuite/gfortran.
