Updated Thomas´ patch fix also fix the case when debug is enabled, otherwise this error occurs:

-Don't do horrible magic with CFLAGS and CXXFLAGS
+MD_CONF_DEBUGGING changes CFLAGS and CXXFLAGS with a horrible magic so disable
+it to prevent compilation errors.
 
-The purpose of the lines being removed is to suppress the
--g<something> option from the CFLAGS or CXXFLAGS, when --enable-debug
-is not used. This is stupid because it is up to the user to pass these
-flags or not.

-But it is not only stupid, but utterly broken: if your CFLAGS contains
-a flags like -mfloat-gprs=double, then this option gets truncated to
--mfloat simply because the option contained the -g string!
