toolchain-scripts: export the target endianism and word size

Browse Source 
Some build systems (notably, Meson) like to be told when cross-compiling
what the target endian and word size is.  We don't have these exported
via the variables, so add them using siteinfo as a source of data.

(From OE-Core rev: c2fee816cae6dbedcb40f15be4a1b9ee91757a64)
