Unless I'm mistaken, this piece of code copying gconv libraries is used
for both the internal and external toolchain backends, no? If that's
the case, then using TOOLCHAIN_EXTERNAL_* here seems wrong, no?

And indeed, the resulting code is not really nice. For sure not worse
than the average toolchain-external.mk code :-/
