[libunwind] "make install" installs libunwind-common.h.in

[Johan Walles]

With libunwind 0.98 on RHAS21, if I do:

  ./configure
  make
  make install

I get in /usr/local/include:

  libunwind-common.h.in
  libunwind-dynamic.h
  libunwind.h
  libunwind-ia64.h
  libunwind-ptrace.h
  unwind.h

All of those look fine, except for libunwind-common.h.in which should have been 
pre-processed and re-named before being installed.
