+Subject: [PATCH] libstdc++: Do not check getentropy and arc4random for cross builds
+
+The "getentropy" and "arc4random" check may not yield a correct result
+for the cross compile builds because linking is often not available for
+them and the C library headers (notoriously, newlib) may still declare
+these function prototypes even if they are not actually part of the
+final library -- for this reason, this commit disables the "getentropy"
+and "arc4random" checks for non-native builds.
+
+This effectively prevents the std::random_device from making use of
+these functions when `--with-newlib` is specified, which is indeed a
+correct behaviour because the newlib does not provide a default stub
+for the "getentropy" function (also note that the newlib "arc4random"
+implementation internally calls the missing "getentropy" function).
+
+For other C libraries, the `GLIBCXX_CROSSCONFIG` function may hard-code
+the availability of these functions by manually defining
+`HAVE_GETENTROPY` and `HAVE_ARC4RANDOM`, or by calling the
+`GLIBCXX_CHECK_GETENTROPY` and `GLIBCXX_CHECK_ARC4RANDOM` functions.
+
+libstdc++-v3:
+	* configure.ac: Relocate GLIBCXX_CHECK_GETENTROPY and
+	GLIBCXX_CHECK_ARC4RANDOM
+	* configure: Regenerate.
+
