I tried recompiling both binutils and gcc using x86_64 as the target as
follows:
binutils:
configure --target=x86_64-pc-linux
make
make install
This works fine. Then gcc:
configure --prefix=/usr/local --target=x86_64-pc-linux
--enable-languages="c"
make all-gcc
This fails. I get the following error:
