[RFC] Build on OSX

[Masaki Muranaka <monaka@monami-software.com>]

Hello,

I've trying to build cross-gdb on OSX host from CVS head.
And the build was failed with following message:

/usr/bin/ld: warning multiple definitions of symbol _locale_charset
./../intl/libintl.a(localcharset.o) definition of _locale_charset in  
section (__TEXT,__text)
/usr/lib/gcc/powerpc-apple-darwin8/4.0.1/../../../libiconv.dylib 
(localcharset.o) definition of _locale_charset


It is well known issue. OSX (maybe also Darwin) hosts
need to link 'resolv' library beforge libintl.a.

Here is a brute-forced patch. But I don't think this is
the good solution.

Any comments appreciated.
