I see - running parallel make added output past the failure point.

This is the part where it conks out:

(snip)
gcc -mcpu=power7 -pipe -O2 -I/opt/freeware/include -L/opt/freeware/lib64
-L/opt/freeware/lib
-Wl,-blibpath:/opt/freeware/lib64:/opt/freeware/lib:/usr/lib:/lib
-Wl,-bmaxdata:0x80000000 -o fixincl fixincl.o fixtests.o fixfixes.o
server.o procopen.o fixlib.o fixopts.o ../libiberty/libiberty.a
collect2: fatal error: ../libiberty/libiberty.a: not a COFF file
compilation terminated.

Could it be an ld or binutils issue?
