NPTL uses SIGRTMIN (signal 32) to effect thread cancellation. Go's runtime replaces NPTL's signal handler with its own, and ends up aborting if a C library that ends up calling pthread_cancel is used. This patch prevents runtime from replacing NPTL's handler. Fixes #6997. R=golang-codereviews, iant, dvyukov CC=golang-codereviews https://golang.org/cl/47540043
