If you need EABI for PPC, it should be done with a new config option + corresponding code in powerpc.sh. That is, exactly what you did, but conditionaly on a config option. Of course, EABI and SPE are probably incompatible, so both should be guarded from each other, for example with a choice: config ARCH_ppc_ABI string default "" if ARCH_ppc_ABI_DEFAULT default "eabi" if ARCH_ppc_ABI_EABI default "spe" if ARCH_ppc_ABI_SPE choice bool prompt "ABI" default ARCH_ppc_ABI_DEFAULT config ARCH_ppc_ABI_DEFAULT bool prompt "default" config ARCH_ppc_ABI_EABI bool prompt "EABI" config ARCH_ppc_ABI_SPE bool prompt "SPE" endchoice And in the script, something like: CT_TARGET_SYS="gnu" case "${CT_ARCH_ppc_ABI}" in "") ;; eabi) CT_TARGET_SYS="eabi" ;; spe) case "${CT_LIBC}" in glibc|eglibc) CT_TARGET_SYS="gnuspe" ;; esac ;; esac Adapt to your own needs and to reality (eg. it might be "gnueabi" instead of simply "eabi"). > 2.

The tuple will always contain the vendor string. If you provide an empty vendor string, it gets replaced with "unknown". It is however possible to create aliases, and for each tool (eg. gcc, ar, as, ld...), a symlink is made that points to the corresponding full-tuple tool. If you want shorter aliases, you have two possibilities: - use the sed expression to mangle the tuple. In your case, that would be something like: CT_TARGET_ALIAS_SED_EXPR="s/-unknown-/-/;" - use a constant alias, in your case, something like: CT_TARGET_ALIAS="powerpc-eabi" - use both of the above In any case, the tuple will always contain the vendor string, and aliases will simply create symlinks.
