[U-Boot] [RFC PATCH v2 12/20] sandbox: Force command sections to be 4-byte aligned

[Simon Glass]

By default sections are 16-byte aligned on some architectures, but the
command name structure (struct cmd_tbl_s) does not have padding to
16 bytes. This change reduces the alignment to 4-bytes so that the command
table can be accessed correctly on any architecture.

(Note: this needs doing properly)
