+[PATCH] Do not set CC_FOR_BUILD flags
+
+Upstream-status: Pending
+
+AC_WIRESHARK_COMPILER_FLAGS_CHECK() is checking which options CC is supported,
+and put the supported options into CFLAGS, but it should not put them into 
+CFLAGS_FOR_BUILD. since CC and BUILD_CC can be different, CFLAGS_FOR_BUILD is
+used by BUILD_CC 
+
+BUILD_CC is used to generated host tools, do not use the gcc's optimised options,
+do not effect the running of host tools. so do not set CC_FOR_BUILD flags.
