microblaze: Overwrite default GCC-5.x behavior

From GCC-5.x version the default mode for C is -std=gnu11
instead of -std=gnu89 but the is still the code in u-boot which doesn't
full fill gnu11 standard. Enable gnu89 inlining.

https://gcc.gnu.org/gcc-5/porting_to.html (go through the
“C languages issues” section).
