[Bug target/39448] New: cross compile for avr mangles path in configure

["chris dot kiick at sun dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Trying to compile avr-gcc on OpenSolaris.  gcc 3.4.3 installed on host, using
sources for 4.3.3.  Make eventually errors off with "cannot compute suffix of
object files".  A look in config.log shows weird paths:
/export/home/ck242721/avr/avr/bin/as: not found.

Binutils installed in /export/home/ck142721/avr/bin with avr- prefix.
 ./configure --target=avr --prefix="/export/home/ckiick/"
--program-prefix="avr-" --enable-languages=c --with-gmp=/usr/local
--with-mpfr=/usr/local
note: gmp and mpfr are installed an in LD_LIBRARY_PATH.

error:

path of avr-as is /export/home/ckiick/avr/bin/avr-as
I've tried using different paths with --prefix but it still does the same
thing.
