David Given c569ca15d8 Clean up how the language libraries refer to plat headers; they should be using 
the +pkg forms of the rules and getting the headers via the paths in descr,
rather than depending on the +headers version.

David Given c5aff6fc2e Change dependency from simplerule{} with a dependency but no outputs to an 
installable; otherwise, the dependency would be built, but the result wouldn't
get added to the header path and so wouldn't be seen.

George Koehler 0d0495e818 Install only 1 copy, not 2 copies, of osx headers. 
Before this commit, the headers in plat/osx/include got installed
twice into PLATIND/osx386/include and PLATIND/osxppc/include.  This
commit installs them once into PLATIND/osx/include and changes both
descr files to find them.

Several rules in lang/ depend on plat/osx386/include+headers or
plat/osxppc/include+headers.  They each become a simplerule that
depends on plat/osx/include+headers.

George Koehler 02fb480217 Commit a preview of osx386 and osxppc as new platforms. 
These produce Mach-o executables for Mac OS X on Intel or PowerPC
processors.  Our code generator for PowerPC (mach/powerpc) still has
bugs.  Some examples seem to run, but startrek crashes.  Our code
generator for Intel (mach/i386) is better.

There is a problem with job control.  If you run paranoia or startrek,
then suspend the job (^Z) and resume it ('fg' in bash), then read(2)
might fail with EINTR.
