SUBDIR builds now happen *after* the current directory, to alleviate
problems caused by the including of _hsc.o files in cbits libs - if
the .hsc file was touched and we recurse into the cbits lib first,
then hsc2hs got run in the cbits lib generating a bogus Foo.hs file in
the current directory which refers to ../Foo_hsc.h.
There was a comment saying that the SUBDIR builds were first because
of something to do with building DLLs in hslibs, but didn't give any
more detail. If/when DLLs are re-enabled we can revisit this.
