[bug-gnu-libiconv] configure using iconv.m4 on 64-bit systems failing

[Ben Taylor]

It appears that the iconv.m4 for autoconf is not really designed to handle
more than one processor definition.  I have libiconv compiled on Solaris
for both 32-bit and 64-bit libraries.  As an example, when I try to build
gnupg, the configure script pulls the 32-bit version (actually the full path
name instead of -liconv) which fails because I'm compiling in a 64-bit
environment.  I'm far from an autoconf wiz, so was wondering if anyone
could think about how I can get around this?

THanks
