+Subject: [PATCH] 00452: Properly apply exported CFLAGS for dtrace/systemtap
+ builds
+
+When using --with-dtrace the resulting object file could be missing
+specific CFLAGS exported by the build system due to the systemtap
+script using specific defaults.
+
+Exporting the CC and CFLAGS variables before the dtrace invocation
+allows us to properly apply CFLAGS exported by the build system
+even when cross-compiling.
