+The "use BX" option is now a suggestion that BX be used if available.\r
+Use a macro to detect if BX is available at build time. If so, and\r
+the user requested it be used, then use it. Otherwise, error out.\r

+References: <1294533910-19305-1-git-send-email-yann.morin.1998@anciens.enib.fr>\r
+\r
+Add three new blind options to set use of Thumb mode:\r
+- COMPILE_IN_THUMB_MODE\r
+ - if set, CFLAGS will contain -mthumb\r
+ - if unset, the compiler's default is used\r
+- HAS_THUMB\r
+ - CPUS with Thumb instruction set can select this\r
+ - use of BX depends on this\r
+- FORCE_THUMB\r
+ - CPUs that are Thumb-only must select this\r
+ - this selects: HAS_THUMB, COMPILE_IN_THUMB_MODE and USE_BX\r
+\r
+Also, remove leading space in Rules.mak.\r
