You certainly are abusing NOTOOLS.  NOTOOLS is only for saving time
in non-cross builds.  Most tools are cross tools (although the current
Makefile doesn't really support building them as such).  Defining NOTOOLS
should give *no* tools (and failure of the build when the first missing
tool is invoked).  However, most tools are created by `make all', so if
they haven't already been created as cross-tools by the `make build-tools'
step, then they will be created as target tools later.  Target tools
normally don't run unless target == host, but in the special case of
host == i386-aout and target == i386-elf, they apparently work if they
are built static.  To get them built static, you should use
`NOSHARED=yes make world' instead of hacking dozens of Makefiles.
This builds everything static, which is good enough for bootstrapping.
