[BZ #10283] localedef: align fixed maps to SHMLBA
Many Linux arches require fixed mmaps to be aligned higher than pagesize, so use the SHMLBA define as it represents this quantity exactly. This fixes spurious errors seen on those arches like: cannot map archive header: Invalid argument URL: http://sourceware.org/bugzilla/show_bug.cgi?id=10283 Reported-by: CHIKAMA Masaki <masaki.chikama@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
