ensures the builds are not broken It doesnt validate the gcc-microblaze
functionality

+Subject: [PATCH 11/63] [Patch, microblaze]: Fix the Microblaze crash with
+ msmall-divides flag Compiler is crashing when we use msmall-divides and
+ mxl-barrel-shift flag. This is because when use above flags
+ microblaze_expand_divide function will be called for division operation. In
+ microblaze_expand_divide function we are using sub_reg but MicroBlaze doesn't
+ have subreg register due to this compiler was crashing. Changed the logic to
+ avoid sub_reg call
