move libgcc.h to include/linux
Introducing a new include/lib directory just for this file totally messes up tab completion for include/linux, which is highly annoying. Move it to include/linux where we have headers for all kinds of other lib/ code as well. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
