x86_64-solaris

[Karl Berry]

Hi Ben - I received a report that the current config.guess returns
i386-pc-solaris2.11 when it should be x86_64-pc-solaris2.11. See below
for details + possible patch. I don't know if it is possible to rely on
isainfo as the user suggests. But sure hope it can be fixed somehow.
--thanks, karl.

No this is not working properly! It reports that  my system is

i386-pc-solaris2.11

while it should report that it is

œôòëx86_64-pc-solaris2.11

The problem is that by default the compiler generates 32bit binaries
regardless of the system. And since config.guess  uses the compiler
to deduce the system it guesses... bananas. œôòëThis is a little patch that
solves this problem:
