package/rocksdb: fix C++ tests This will fix a build failure on xtensa and nios2 that missed -faligned-new Fixes: - http://autobuild.buildroot.org/results/58bf25a16984c4d5f3ce0e26a56712410b67c53a - http://autobuild.buildroot.org/results/718fee3d20ef00ffa5c3e617a036cf2b82c97411 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

Subject: [PATCH] build_tools/build_detect_platform: fix C++ tests
Replace -o /dev/null by -o test.o when testing for C++ features such as
-faligned-new otherwise tests will fail with some bugged binutils
(https://sourceware.org/bugzilla/show_bug.cgi?id=19526):
