WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

WARNS is now default to 6.

Remove end of line whitespace.

Always define LD_32_PRELOAD so it works for 32 bits binaries on
64 bits platforms. Let rtld(1) decide if it needs to honor it

While here, fix a small bug in error reporting when asprintf(3)
returns an error.

entry point.
