[PATCH v1 1/1] gas: microblaze: Add mlittle-endian and mbig-endian flags

[Neal Frager]

Added support in gas for mlittle-endian and mbig-endian flags
as options.

Updated show usage for MicroBlaze specific assembler options
to include new entries.

This patch has been tested for years of AMD Xilinx Yocto
releases as part of the following patch set:
