Possible gcc-4.3 regression wrt bootstrapping the toolchain

[Jonas Meyer]

Hello
I tried building a crosstoolchain with gcc-4.3. The way it worked with
earlier versions doesn't work with 4.3 anymore because make all-gcc
doesn't build libgcc at all. It doesn't fail, it just doesn't build
it.
If this is intended behaviour I'd be glad for anyhints how to
bootstrap a toolchain now.
Thanks, Jonas
