[Bug libc/10855] New: localedef fails to create locale-archive on SPARC

["aurelien at aurel32 dot net" <sourceware-bugzilla at sourceware dot org>]

localedef now reserve memory with mmap and MMAP_PRIVATE, and later remap this
memory area using MMAP_SHARED | MMAP_FIXED. This does not work on SPARC with a
64-bit kernel as MMAP_PRIVATE and MMAP_SHARED have different alignement
constraints. MMAP_PRIVATE must be aligned on the page size (4kB), while
MMAP_SHARED must be aligned on the L1 D-Cache size (16kB).

The solution is to reserve and remap the memory with the same flags. The
attached patch does that.
