Small tweak here. glibc failed to build with the simple minded gcc with
this error:

So I symlinked libgcc_eh.a to libgcc.a, as it seems most of its objects
ended up in there with --disable-shared. That made glibc compile at
least. Hopefully it also works correctly. :)

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
