Log Message:
libc:
Internally rename __sigaction14 to __libc_sigaction14.  Provide a
weak alias of __sigaction14 -> __libc_sigaction14.

libpthread:
Use __libc_sigaction14 to actually register the signal handler, rather
than using __sigaction_sigtramp() directly with a hard-coded trampoline
version.  While we don't actually use the libc trampoline, we want to
avoid depending on any COMPAT_* kernel options down the road (this is
already the case for the VAX port).

Be explicit about which version of the signal interface we're interposing
(...14), and build pthread_sig.c with __LIBC12_SOURCE__ (required to get
the libc-internal interfaces).
