Thanks for the new version.
One thing I noticed is that without additional changes[1] this
patch just makes 'configure' script to fail the library check,
because 32bit library can't be linked with 64bit binary it checks:
checking for unw_backtrace in -lunwind... no
But it should work as intended with the patch I posted:
[1] https://patchwork.ozlabs.org/patch/1171259/
Note that I replaced $BUILD_ENV with $M32 variable, so one of the
patches will need to be updated depending on the order of applying.
i.e. following diff should be squashed to one of them:
-if [[ $BUILD_ENV =~ "-m32" ]]; then
+if [ "$M32" ]; then
Other than that,
