[Patch] tr1/8.4 + configury

[Paolo Carlini]

Hi,

the below adds the simple bits required for 8.4 and some configury: I'm
adding a separate procedure, checking the various headers for the
functions specifically required for TR1. For the moment, cannot be
disabled by a configure option, I think it's correct, because at
variance with the existing [GLIBCXX_ENABLE_C99] we are *not* "polluting"
(in the sense of C++03) namespace std anyway. But maybe the procedure
will become more complex, in the future...

Tested x86-linux, would commit later today.

Paolo.
