for each $MACHINE_ARCH we have compat libraries to build for, give a list
of ABIs to target. for amd64 and sparc64, we use the old i386 and sparc
subdirectories. for mips64, we build both o32 and n64 libraries.

these files are not yet used, but will be shortly.

Apply patch (requested by mrg in ticket #1499):

src/compat version 2. this allows building any number of alternate
library / program target ABIs. rather than duplicating the list of
subdirs and Makefiles to build, it re-traverses the necessary ones.
details:
- add support for MAKEDIRTARGETENV to share/mk
- renames LD32DIR to MLIBDIR
- fixes library builds for some subdirs (more was built than needed)
- fixes /bin & /sbin apps in compat mode
- reduces complexity in src/compat and the rest of the tree
- updates ldd netbsd32 support

merge the new src/compat build into the place it was actually born.
this replaces the old src/compat with a method that re-traverses the
library directories with a different set of flags, and is capable of
building more than one compat ABI.
