gawk sneaks in x86_64 which is not set in universal_archs on Leopard

[barracuda156]

Macports is configured to build for ppc+ppc64 when +universal is specified:

universal_archs     	ppc ppc64

Portfile refers to README.macosx, which talks about a specific case of M1. I believe, that should be limited to aarch64 and the following should not happen on PowerPC:

That -arch x86_64 isn’t coming from the Portfile, it’s coming from the upstream gawk build itself. The --disable-pma in the Portfile is what circumvents it. Clearly the upstream had not contemplated ppc or ppc64. In fact, it won’t work for builds intended to be 32-bit x86 either.

I had tried to let the PMA feature work where it could, but based on this report, disabling it when ${build_arch} eq "arm64" isn’t good enough. It really needs to be disabled when ${build_arch} ne "x86_64". Either that, or the PMA feature could just be unconditionally disabled altogether. I’d be in favor of that.
