+Subject: [PATCH] cmake: Add check for 64bit builtin atomics
+
+Compilers for some architectures e.g. RISCV32 do not have 64bit atomics
+therefore, its important to deduce that and use it to pass right flags to
+compiler to use them, e.g. h2o module
+
+Fixes
+nection.c.o): in function `h2o_create_connection':
+| /usr/src/debug/netdata/1.47.1/src/web/server/h2o/libh2o/include/h2o.h:1917:(.text.create_conn+0x5e): undefined reference to `__sync_add_and_fetch_8'
+| collect2: error: ld returned 1 exit status
+
+Upstream-Status: Submitted [https://github.com/netdata/netdata/pull/18565]
