[Samba] iconv detection on Irix 6.5

[Jason Mader]

Samba 3.0.2 and earlier on Irix 6.5 haven't been detecting libiconv, 
even when using the --with-libiconv directive.

I found it best to configure libiconv as,
   ./configure --prefix=/opt --libdir=/opt/lib32
because /opt/lib32 is in ldd's search path.

And before configuring Samba to make three changes to the configure 
script to properly detect libiconv and build the test programs.  I've 
attached the diff.  Changing LOOK_DIRS="/usr /usr/local /sw" to also 
include /opt might be useful for Irix builds.
