    I think so. I just rebuilt the thing and still no love:

    I hope warnings like this (one for each and every file, it seems):

    scripts/mod/empty.c:1: warning: -ffunction-sections disabled; it makes
    profiling impossible

    and

    ld: warning: i386:x86-64 architecture of input file
    `arch/x86_64/boot/compressed/head.o' is incompatible with i386 output

    don't indicate anything particularly maleficent.
