./configure cannot execute a compiled binary for one of its tests
(because the binary is compiled for a different architecture - you're
cross-compiling).

I am crosscompiling for the EM7075, using the 'sourcery' toolchain.
For crosscompilation I have created the following script. I don't use
autogen.sh.

martin at martindesktop ~/EM7075 $ cat
compile_scripts/samba-3.5.10/compile_samba-3.5.10.sh
#!/bin/sh

# Set variables
export CFLAGS="-EL -O2"
export CC="/opt/Sourcery_G++_Lite/bin/mips-linux-gnu-gcc -O2"
export PATH=/opt/Sourcery_G++_Lite/bin:$PATH
export LDFLAGS=" -EL -s
-L/opt/Sourcery_G++_Lite/lib/gcc/mips-linux-gnu/4.3.3/el"
export STRIP="/opt/Sourcery_G++_Lite/bin/mips-linux-gnu-strip"
export LD="/opt/Sourcery_G++_Lite/bin/mips-linux-gnu-ld"

Also note that I have adapted the following lines in the Makefile to
get the locations right:

prefix=/opt
DESTDIR=/home/martin/EM7075/result/samba-3.5.10
BASEDIR= /opt

You must adapt it after running ./configure.

HTH,
