+Subject: [PATCH 3/4] debug prefix map
+
+We want to pass ${DEBUG_PREFIX_MAP} to gcc commands and also pass in
+ --debug-prefix-map to nasm (we carry a patch to nasm for this). The
+tools definitions file is built by ovmf-native so we need to pass this in
+at target build time when we know the right values so we use the environment.
+
+By using determininistc file paths during the ovmf build, it removes the
+opportunitity for gcc/ld to change the output binaries due to path lengths
+overflowing section sizes and causing small changes in the binary output.
+Previously we relied on the stripped output being the same which isn't always
+the case if the size of the debug symbols varies.
