I have found an interesting problem:

On a sparc64 machine, I do

  cd /usr/src/regress/usr.bin/make
  make
  make regress

and everything works fine. However, if I use the $TOOLDIR make wrapper instead,
i.e. after proper cleaning of the previous:

  cd /usr/src/regress/usr.bin/make
  ${TOOLDIR}/bin/nbmake-sparc64
  ${TOOLDIR}/bin/nbmake-sparc64 regress

the regression test fails.

Has anyone else seen this (on other archs)?
