hmm, nv,. 

guess i just needed to run

ARCH=arm make clean
-------


HOSTCC  scripts/mod/mk_elfconfig
cc1: error: unrecognized command line option ‘-mlittle-endian’
cc1: error: unrecognized command line option ‘-mno-thumb-interwork’

I checked out git master and tried to cross compile an arm kernel for my
sheevaplug

It fails with linker errors:

/usr/bin/ld.bfd.real: scripts/mod/file2alias.o: Relocations in generic
ELF (EM: 40)
/usr/bin/ld.bfd.real: scripts/mod/file2alias.o: Relocations in generic
ELF (EM: 40)
/usr/bin/ld.bfd.real: scripts/mod/file2alias.o: Relocations in generic

ELF (EM: 40)
scripts/mod/file2alias.o: could not read symbols: File in wrong format
collect2: ld returned 1 exit status

where it appears that it isn't calling the cross-toolchain
(/usr/bin/arm-linux-gnueabi-ld)

I have 
CONFIG_CROSS_COMPILE="arm-linux-gnueabi-"


I did a full git bisect and
