libcompiler_rt now part of FreeBSD's base system

Hello all,

I just committed libcompiler_rt.a to HEAD. Even though I don't expect
serious issues -- especially not on the tier 1 architectures -- be sure
to contact me in case something goes wrong. I hooked it up to the build
in a separate commit, so if your system starts to act weird, just revert
r215127.

Thanks to everyone who helped testing this!

>   Replace libgcc.a by libcompiler_rt.a.
>   
>   libcompiler_rt.a is a BSD licensed C language runtime, which implements
>   many routines which are linked into binaries on architectures where
>   certain functionality is missing (e.g. 64 bits mul/div on i386).
>   
>   Unfortunately, libcompiler_rt cannot replace libgcc entirely. Certain
>   features, such as an unwinder for exception handling, are missing.
>   That's why only libgcc.a is replaced for now, because this one does seem
>   to be complete.
