[PATCH] extra/locale: Mark __codeset_8_bit_t as packed.

[Will Newton]

gen_ldc writes offsets into the __locale_mmap_t structure. This
relies on the host system having the same struct offsets as the
target. On some architectures structs are aligned to 4 byte
boundaries and for these targets it is required for the struct to
be packed so that it is more likely to match the host system
(typically x86 which does not align structs).
