Subject: [meta-oe][PATCH v2] luajit: test SITEINFO_BITS instead of maintaining a list of 32bit targets
Precedence: list

When cross compiling, the word size of the compiler set via HOST_CC
must match the word size of the target. That's achieved by appending
"-m32" to BUILD_CC_ARCH if the target word size is known to be 32bits.

Unfortunately the current list of over-rides may not cover all cases.
Using SITEINFO_BITS is a more generic solution.
