libstdc++: Support getentropy and arc4random in std::random_device
This adds additional "getentropy" and "arc4random" tokens to
std::random_device. The former is supported on Glibc and OpenBSD (and
apparently wasm), and the latter is supported on various BSDs.
libstdc++-v3/ChangeLog:
* acinclude.m4 (GLIBCXX_CHECK_GETENTROPY, GLIBCXX_CHECK_ARC4RANDOM):
Define.
* configure.ac (GLIBCXX_CHECK_GETENTROPY, GLIBCXX_CHECK_ARC4RANDOM):
Use them.
* config.h.in: Regenerate.
* configure: Regenerate.
* src/c++11/random.cc (random_device): Add getentropy and
arc4random as sources.
* testsuite/26_numerics/random/random_device/cons/token.cc:
Check new tokens.
* testsuite/26_numerics/random/random_device/entropy.cc:
Likewise.
