Hrmpf.  On Solaris, we add '${wl}-z ${wl}text' to archive_cmds and
archive_expsyms_cmds unconditionally, as opposed to only with
-no-undefined.  I wonder why that is the case.

But of course I also wonder why the problem happens at all.  iconv.o is
built with PIC, so that would indicate a bug in GCC, or possibly the
assembler or linker.  Which GCC version is this, and how was it
configured?  Any chance you can create a small reproducible example to
send to the GCC bugzilla?

Sorry for them, but I don't think Google is accepting bug reports for
Libtool nor GCC.  I don't recall a prior report for gcc on Solaris on
the Libtool lists (unlike for a C++ compiler on Solaris).
