[bug-gnu-libiconv] Problems building a 64-bit iconv on Solaris x86

[Dr. David Kirkby]

I've built iconv on a number of different Solaris systems

* 32-bit and 64-bit
* OpenSolaris and Solaris 10
* SPARC and x86.

But two different systems will not build iconv. These are

 * Solaris 10 x86 64-bit (hostname fulvia)
 * OpenSolaris 11.2008 on x86 hardware. (hostname disk.math.washington.edu)

A third one, running a later version of OpenSolaris will however build iconv. 
All the failures have occured when building 64-bit versions - so far, everything 
has been fine with 32-bit versions.

A table showing my results on various Solaris systems can be seen here. Note it 
includes both Solaris and OpenSolaris, SPARC and x86, 32-bit and 64-bit builds.

A log file of a 64-bit failed build on host 'fulvia' running Solaris 10 update 5 
05/2008 can be seen here

The config.log can be seen here.

A little bit of information is given on a build failure on another machine 
(hostname disk.math.washington.edu), which runs OpenSolaris.

I did not pay too much attention to this failure, as the system has rather old 
versions of compilers and other things. But the failure on the host 'fulvia' is 
more worrying, as that has the latest gcc and a recent, if not the latest binutils.

In all cases, the Sun linker was used. This includes both successful and 
unsuccessful builds, on both SPARC and x86.

Would you have any thoughts on what might be the problem on this 64-bit build 
problems on x86 systems? Can you suggest a workaround?

I can run any tests anyone suggests.
