Well, in the end, I managed to get things working for Buildroot. I
considered that the GCC support libraries (libgcc_s, libstdc++, etc.)
can be in a separate directory, outside the sysroot, and I tweaked our
external toolchain logic to support this case. It seems to work fine.
I'm not sure it's really readable, but the change I've done to
Buildroot is
http://git.buildroot.net/buildroot/commit/?id=e1f0804cc11706648f33a96d68e613b8d6593db3.
I've also added support for Linaro 2012.04, and I've successfully
generated and booted an ARM Linux system with Buildroot and the Linaro
2012.04 toolchain.
Thanks!
Thomas
