ada: c++: Get rid of libposix4, librt on Solaris
I recently noticed that neither libposix4 nor librt are needed on
Solaris 11 any longer:
* libposix4 was renamed to librt in Solaris 7 back in 1998.
* librt was folded into libc in the OpenSolaris timeframe, leaving librt
only as a filter on libc. Thus, it's no longer needed on either
Solaris 11 or Illumos.
The following patch removes both uses. At the same time, Ada's use of
libthread has gone: it was folded into libc in Solaris 10 already.
TIME_LIBRARY and friends in g++ are likewise removed: Solaris was the
only user.
Bootstrapped without regressions on i386-pc-solaris2.11,
sparc-sun-solaris2.11, and x86_64-pc-linux-gnu.
