That's a string to pull.
I've stucked with EGLIBC too, but
make ARCH=ppc64 "CC=gcc -m64"
tossed forward until got
cc1: error: unrecognized command line option "-mno-vsx"
make[2]: *** [/home/meres5/src/eglibc/ports/gmon/mcount.o] Error 1
Why is so painful to say no to a nonexistent thing?
LOL again.
Facing interesting hours though...
