The gcc 5 change its default standard from gnu89 to gnu11. These two
standards do have different semantics for inline functions. And the
gcc 5 will emit the following errors on the "extern inline" functions:
arch/powerpc/cpu/mpc8xxx/fsl_lbc.o: In function `ld_le16':
./arch/powerpc/include/asm/byteorder.h:12: multiple definition of `ld_le16'
arch/powerpc/cpu/mpc8xxx/fdt.o:./arch/powerpc/include/asm/byteorder.h:12:
first defined here
Fix these build errors by using "-fgnu89-inline" to enforce the gnu89
inline semantics as suggested in [1].
