This looks to me like you made a typo on the command line. You need two
dashes before the --prefix option, not one. That's why gcc didn't know where
to look for its files.

They're based on $prefix and compiled directly into the gcc.exe driver
program - hence the problems!

Yes, this is fine; you just untar gcc-core plus whatever additional
languages you want into the same place, and the standard configure file from
gcc-core will include all of them in your build.
