[review] Check for sigprocmask in common.m4
Change URL: https://gnutoolchain-gerrit.osci.io/r/c/binutils-gdb/+/165

Check for sigprocmask in common.m4
I noticed that gdbsupport uses HAVE_SIGPROCMASK, but common.m4 does
not check for it. This means that gdbserver may not compile some
gdbsupport code properly. This patch fixes this error.
