The file libgcc/generic-morestack-thread.c refers to EAGAIN, so for
cleanliness it should really #include <errno.h>. This does not
introduce any new build problems, as generic-morestack.c already
#includes <errno.h> anyhow. This patch adds the #include. Bootstrapped
and tested on x86_64-unknown-linux-gnu. Committed to mainline.
