[tlbuild] PPC builds

[Mojca Miklavec]

Hi,

Not too important. I tried to compile PPC binaries without much success:

depbase=`echo pmx-src/scor2prt.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
/opt/local/bin/gcc-mp-7 -DPACKAGE_NAME=\"pmx\ \(TeX\ Live\)\"
-DPACKAGE_TARNAME=\"pmx--tex-live-\" -DPACKAGE_VERSION=\"2.8.4\"
-DPACKAGE_STRING=\"pmx\ \(TeX\ Live\)\ 2.8.4\"
-DPACKAGE_BUGREPORT=\"tex-k at tug.org\" -DPACKAGE_URL=\"\"
-DPACKAGE=\"pmx--tex-live-\" -DVERSION=\"2.8.4\" -DSTDC_HEADERS=1

mv -f $depbase.Tpo $depbase.Po
/opt/local/bin/gcc-mp-7  -g -O2   -o scor2prt pmx-src/scor2prt.o libf2c.a

collect2: fatal error: dsymutil terminated with signal 6 [Abort trap]

Some people hinted that this might be a compiler error. I'll try with
a different compiler, but as I already said, I would not worry if this
doesn't work at the end and we can simply drop the platform.
