40    <para>Existing multilib distributions alter gcc to default to 32-bit
41    output.  Because our gcc defaults to 64-bit, we need to pass appropriate
42    options to both the compiler and the linker.  The Makefile already
43    overrides any CC and ignores LDFLAGS in favour of its own variables, so we
44    need to use the following seds for a successful compile and install.</para>

76      correctly without the second sed, but will fail to load linux,
77      requiring you to use OF or a rescue disk to boot.</para>
