#62332: Cannot build gcc7 with +universal on Intel Tiger

-------------------------+--------------------
 On a fresh install of MacPorts on Intel Tiger, with no changes made to any
 configuration files, when I run:

 {{{sudo port install gcc7 +universal}}}

 I am told:

 {{{
 --->  Computing dependencies for gcc7
 Error: Cannot install gcc7 for the archs 'i386 x86_64' because
 Error: its dependency gmp does not build for the required archs by default
 Error: and the configured universal_archs 'i386 ppc' are not sufficient.
 Error: Follow https://guide.macports.org/#project.tickets to report a bug.
 Error: Processing of port gcc7 failed
 }}}

 This is weird. From what I understand, on Tiger, +universal should cause
 ports to build as ppc and i386. So why is it trying to install gcc7 for
 x86_64, and not for ppc? Can I tell it to not do that?

 Please feel free to tell me if I'm doing something wrong, but this feels
 like a bug.
