Log:
Remove the -m64 sections from binutils and gcc pass 1. Tests show the 32-bit
binaries produce the wanted 64-bit code.

<para>This forces <command>gcc</command> to prefer the linker from

- variable is empty. The parameter forces <command>gcc</command> to
build
- 64-bit binaries. Using that parameter here and for the next package
- ensures creation of a linker, assembler and compiler that will in turn
- create only 64-bit binaries. This is necessary since currently this
book
- does not support the creation of multilib systems, i.e., those with
both
- 32-bit and 64-bit libraries. This will only make a difference on
hosts that
- are themselves multilib and employ a compiler that creates 32-bit
binaries
- by default.</para>
