Producing GCC binaries requires a working C toolchain (C compiler, C
library, assembler, linker,...) for the "host" system, in your case
for OS X 10.5!  The GCC "sources" are mostly in 'C' language, so a
working C compiler for the host is required to compile them. In order
to make the executables for the "OS X to Linux/PPC" crosscompiler,
producing executables for OS X 10.5 MUST work !

The error tells that now you cannot produce any executables for OS X
10.5 with the installed "Xcode" (what on earth is that?) !

This says "powerpc-apple-darwin9"... Is that really the same thing
as "a PowerPC OS X 10.5 system" ?  Ie do you really have GCC etc
made for OS X 10.5 ? Not one made for OS X 9.x ?
