Subject: [PATCH] make all .o files depend on *_impl.h and libc.h

hopefully the annoyance of this will be minimal. these files all
define internal interfaces which can change at any time; if different
modules are using different versions of the interfaces, the library
will badly break. ideally we would scan and add the dependency only
for C files that actually reference the affected interfaces, but for
now, err on the side of caution and force a rebuild of everything if
any of them have changed.

this commit is in preparation for the upcoming ssp overhaul commit,
which will change internals of the pthread struct.
