[Bug bootstrap/26814] New: Can't build a 64-bit C compiler on darwin-ppc

["lucier at math dot purdue dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

Configured and built with

#!/bin/tcsh
/bin/rm -rf *; ../configure --prefix=/pkgs/gcc-4.1.0 --with-gmp=/sw/
--with-mpfr=/sw/ --with-as=/usr/local/odcctools-20060123/bin/as
--with-ld=/usr/local/odcctools-20060123/bin/ld --enable-languages=c; make -j 8
bootstrap BOOT_CFLAGS='-mcpu=970 -m64 -O2 -g' >& build.log 

Bootstrap fails with

stage1/xgcc -Bstage1/ -B/pkgs/gcc-4.1.0/powerpc-apple-darwin8.5.0/bin/  
-mcpu=970 -m64 -O2 -g -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes

ld64 failed: in
../build-powerpc-apple-darwin8.5.0/libiberty/libiberty.a(hashtab.o), not a
valid ppc64 mach-o file

which seems to be right:

gcc -c -DHAVE_CONFIG_H -g -O2 -I/sw//include -I/sw//include -I.
-I../../../libiberty/../include  -W -Wall -pedantic -Wwrite-strings
-Wstrict-prototypes ../../../libiberty/hashtab.c -o hashtab.o
