More findings....

Thanks to RP we finally figured out why this was happening:
./arm-angstrom-linux-uclibcgnueabi-gcc -o /tmp/testout /tmp/test.c 
/opt/angstrom/arm/lib/gcc/arm-angstrom-linux-uclibcgnueabi/4.2.2/../../../../arm-angstrom-linux-uclibcgnueabi/bin/ld:
cannot find libc.so.6
collect2: ld returned 1 exit status

The problem is in meta-toolchain.bb - RP fixed it in .dev but for .stable this
line also needs to be commented out (not sure about the implications for
glibc):
echo 'GROUP ( libc.so.6 libc_nonshared.a )' >
${SDK_OUTPUT}/${prefix}/${TARGET_SYS}/lib/libc.so


However... one gets to this stage only if gcc-cross-sdk builds, and that's
still a problem. Sometimes it does build, but sometimes it is failing, both -
in .stable and in .dev

I use PARALLEL_MAKE, maybe that could explain the "sometimes" issue?

The failure log of gcc-cross-sdk in from .dev is the same as in .stable, so
this problem still persists (see URL with compile log)

I also noticed that the following message is being printed when building
binutils-cross-sdk, but NOT when building binutils-cross!
"NOTE: Couldn't find shared library provider for libc.so.6"

That must be a clue, after all: gcc-cross-sdk is for some reason looking for
libc.so.6 and already on binutils-cross-sdk OE thinks that libc.so.6 is
missing.

This is also in both - .stable and .dev

I hope this brings us further to the final solution.
