Removing the alarm stub from libcfunc.c will break the build for the
users that only require  a stub definition of alarm, but it also
allows the users that need a working copy of alarm to redefine it.
Meanwhile, the stub users can either add -lnosys to their link or add
an alarm() {} stub to their own project. Chances are good that if
their successful build depends on a stub of alarm, their build also
depends on other stubs not defined by newlib (like pause for example)
and already have a scheme in place for providing them.
