This patch to libgo arranges to define SIGPOLL and SIGCLD if necessary,
as SIGIO and SIGCHLD respectively. This is necessary on GNU/Linux
because SIGPOLL is #define'd as SIGIO before SIGIO is #define'd, and gcc
-fdump-go-spec doesn't understand that. Bootstrapped and ran Go
testsuite on x86_64-unknown-linux-gnu. Committed to mainline and 4.7
branch.
