FYI: $MAKE -e needs SHELL=/bin/sh

On NetBSD 1.5 and OSF1 V4.0, `$MAKE -e' override $(SHELL) with
the SHELL environment variable (this is against POSIX).
This causes failures when running the testsuite from tcsh (for
instance).

The following make sure we always override $(SHELL) when we run
$MAKE -e.

(There is already a few tests that override SHELL=/bin/sh.)

Another solution would be to set SHELL from defs, but I prefer
not to, so we can detect any other place that implicitely use
$SHELL.
