Thank you Koen for the answer. I followed your istructions,


I tryed to use "angstrom-2007.1" DISTRO as you told me, but there are
2 different behaviours depending of kind of building:
 	
>>> if I build a SINGLE PACKAGE (-b option)	
	for example: 
        ~/oe$ bitbake -b myPackages/myhelloworld/myhelloworld_0.1.bb -DD
	
	variables are exported CORRECTLY (with i686-linux- prefix)
        some examples:
		+ export LD=i686-linux-ld
		+ LD=i686-linux-ld

		+ export 'CC=i686-linux-gcc-4.3.1 -mcpu=pentiumpro'
		+ CC='i686-linux-gcc-4.3.1 -mcpu=pentiumpro'

		+ export STRIP=i686-linux-strip
		+ STRIP=i686-linux-strip

		+ export RANLIB=i686-linux-ranlib
		+ RANLIB=i686-linux-ranlib
		
	these i686-linux-* are in ~/oe/myToolchain/cross/bin directory 
        which is in my $PATH

	but the build fails with: | i686-linux-gcc-4.3.1: Success
| + cd
/home/claudiu/oe/oetmp/work/i686-angstrom-linux/myhelloworld-0.1-r0/
myhelloworld-0.1
| + do_compile
| + i686-linux-gcc-4.3.1 -mcpu=pentiumpro
-isystem/home/claudiu/oe/oetmp/staging/i686-angstrom-linux/include,
-I/home/claudiu/oe/myToolchain/cross/include -fexpensive-optimizations

/home/claudiu/oe/oetmp/work/i686-angstrom-linux/myhelloworld-0.1-r0/
myhelloworld.c -o myhelloworld
| i686-linux-gcc-4.3.1: Success
NOTE: Task failed:

log.do_compile.18268
NOTE: package myhelloworld-0.1-r0: task do_compile: failed



>>> if I build bootstrap-image or other package in the metadata
WITHOUT -b option

	for example: ~/oe$ bitbake bootstrap-image -DD

	variables are exported WRONGLY (WITHOUT i686-linux-
        prefix, even if in local.conf I specified the prefix, see the first
        post), because I want to use my toolchain. Some examples:		
                + export LD=ld
		+ LD=ld

		+ export CC=gcc
		+ CC=gcc

 		+ export RANLIB=ranlib
		+ RANLIB=ranlib

		+ export CXX=g++
		+ CXX=g++

	the build fails on "shasum-native" with: | collect2: cannot find 'ld'
| + export BUILD_STRIP=strip
| + BUILD_STRIP=strip
| + cd /home/claudiu/oe/oetmp/work/i686-linux/shasum-native-1.0-r1
| + do_compile
| + gcc -isystem/home/claudiu/oe/oetmp/staging/i686-linux/include -Os
-isystem/home/claudiu/oe/oetmp/staging/i686-linux/include -o oe_sha256sum
main.c sha256.c
| collect2: cannot find 'ld'
NOTE: Task failed:
/home/claudiu/oe/oetmp/work/i686-linux/shasum-native-1.0-r1/temp/
log.do_compile.18246
NOTE: package shasum-native-1.0-r1: task do_compile: failed





Otherwise, if I still use "generic" DISTRO, I have the error specified in
the first post.
The config.log (placed in :
oe/oetmp/work/i686-linux/libtool-cross-1.5.10-r9/temp/log.do_configure.5538)
says the same things as above in the first post. It ends with these lines:
