Ok, here is what is happening.

First, I gave you the wrong advice on the option to get verbose info from ld.
I gave you the hpux option.  The GNU option is `--verbose' or `-Wl,--verbose'
when using the gcc driver.

Here is the linker path on gsyprf11:

SEARCH_DIR("/usr/hppa-linux/lib"); SEARCH_DIR("/usr/lib"); SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib");

Here is where ld found libgcc_s.so.1:
found libgcc_s.so.1 at /usr/local/lib/libgcc_s.so.1

The version of libgcc_s.so.1 in /usr/local/lib is old and appears to have
been built using dwarf2 exception support.

Probably, the version of GCC installed in /usr/local should be removed.
I believe it was the initial port with support for Ada.  However, this
is now part of the regular debian distro.
