OS Specific toolchain - libgcc

[justin]

I added the libgcc part to http://wiki.osdev.org/OS_Specific_Toolchain#GCC_2. I'd like someone more knowledgeable to check it before I steer someone wrong.

I was under the impression libgcc would be built and installed automatically by the other commands in the tutorial (especially the make install-gcc one). It may be, however, that it was installed by the libstdc++ step instead, in which case your commands would be necessary for the situation where c++ is not used. It has been a while since I last ran through the tutorial from scratch. I need to do more testing I guess...

edit: it would appear the make all-target-libgcc step is required when not installing libstdc++. I am also making some changes to support a more recent version of the tools.

True. Maybe it was different in older versions, but libgcc is included in the all-gcc and install-gcc targets. No all-target-libgcc or install-target-libgcc is needed afaik.

I just tried it in 4.7.0 (haven't tried it in any versions between 4.2.1 and 4.7.0) and libgcc wasn't built in the make all-gcc step, so I'll let it stand for now as it is unlikely to cause any harm.
