Important notices: - The snapshot cannot be created for big-endian target in cross-compilation environment on little-endian host using simulator. - In order to have i18n support working on big-endian target, the icudt46b.dat and icudt46b_dat.S files should be generated and upstreamed to ICU repo. - The mjsunit 'nans' test is endian dependent, it is skipped for mips target. - The zlib and Mandreel from Octane 2.0 benchmark are endian dependent due to use of typed arrays.
