From d5293d73b760268a6b200ab7d9323e37700e6a8c Mon Sep 17 00:00:00 2001

Subject: [PATCH] lapi: Define TST_ABI{,32,64} to detect target type

This is meant to be a replacement of __WORDSIZE definition.

Motivation was instead of finding, where all libc define
__WORDSIZE, which is usually used for detecting target type
(at least MUSL defines it in different place than other libc)
we define our own constant.
