+Adding @CROSS_COMPILE@ to CFLAGS_FOR_BUILD causes errors like:
+
+mkbuiltins.o: In function `open':
+/usr/include/x86_64-linux-gnu/bits/fcntl2.h:54: undefined reference to `xopen'
+mkbuiltins.o: In function `read':
+/usr/include/x86_64-linux-gnu/bits/unistd.h:45: undefined reference to `xread'
+collect2: ld returned 1 exit status
+
+when compiling on a 64 bit x86 build system for a 32 bit x86 target since
+config.h confuses the compiler about settings. By removing the option, config.h 
+isn't used and the compiler stops getting confused.
