Define _GLIBCXX_USE_DEV_RANDOM as replacement for _GLIBCXX_USE_RANDOM_TR1
Define and use a new macro with a more descriptive name. Only use the
old macro in <tr1/random.h>.
* acinclude.m4 (GLIBCXX_CHECK_RANDOM_TR1): Replace with ...
(GLIBCXX_CHECK_DEV_RANDOM): New macro with more descriptive name.
Define _GLIBCXX_USE_DEV_RANDOM as well as _GLIBCXX_USE_RANDOM_TR1.
* config.h.in: Regenerate.
* configure: Regenerate.
* configure.ac: Use GLIBCXX_CHECK_DEV_RANDOM instead of
GLIBCXX_CHECK_RANDOM_TR1.
crossconfig.m4: Likewise.
* include/bits/random.h (random_device): Use _GLIBCXX_USE_DEV_RANDOM
instead of _GLIBCXX_USE_RANDOM_TR1.
* testsuite/26_numerics/random/random_device/cons/token.cc: Likewise.
