Argh!  This is not good (and I'm completely confused).  Here's what 
arch/arm/functions has to say:


    case "${CT_ARCH_ABI},${CT_ARCH_ARM_EABI}" in
        *,) ;;
        aapcs,y)
            CT_DoLog DEBUG "'--with-abi=aapcs' is in fact 
'-mabi=aapcs-linux' when used in CFLAGS."
            CT_ARCH_ABI_CFLAGS="-mabi=aapcs-linux"
            ;;
        ,y)
            CT_DoLog WARN "Forcing ABI to 'aapcs-linux' for use with 
EABI."
            CT_ARCH_WITH_ABI="--with-abi=aapcs"
            CT_ARCH_ABI_CFLAGS="-mabi=aapcs-linux"
            ;;
        *,y)
            CT_DoLog ERROR "ABI='${CT_ARCH_ABI}' not supported for EABI."
            CT_Abort "If you know you are right, please edit 
'arch/arm/functions' in crosstool-NG sources."
            ;;
    esac


Unfortunately I know that I'm getting variable sized enums, so I really 
don't know what's going on here.
