poppler @ 22.02.0 does not build on PPC

[barracuda156]

First of all, invoking install on 10.5.8 fails with an odd message:

--->  Computing dependencies for poppler..
Error: Cannot install clang-7.0 for the arch 'powerpc' because
Error: its dependency python27 does not build for the required arch by default
Error: and the configured universal_archs 'ppc ppc64' are not sufficient.
Error: Follow https://guide.macports.org/#project.tickets if you believe there
is a bug.

When installation is invoked with sudo port -v -n install poppler -universal configure.compiler=macports-gcc-7 build_arch="ppc" the build fails on this:

16. S. I used -universal, because its dependency nspr fails to build as universal: ​https://trac.macports.org/ticket/64651

It looks like something in the Portfile is blacklisting GCC, though I'm not sure what. If GCC is supported by poppler then the issue is probably worth reporting upstream. This (non-poppler) issue seems similar:

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #64808.

The problem that the gcc compiler wasn't being used was fixed in MacPorts 2.7.2.

poppler: fix build with GCC7
