description:
Reset MAKELEVEL=0 to fix bad gmake/bsdmake interactions.
Our make(1) now sets $MAKELEVEL. While this should cause no harm, gmake
detects a non-zero $MAKELEVEL and automatically sets "w" in $MAKEFLAGS
for subordinate makes, in order to print the entry and exit directories.
Our make, does not understand -w, so it prints an error message and exits.

In order to catch this everywhere (since cmake for example can invoke
either our make or gmake depending on how it feels), we reset the variable
for any top level command. This effectively reverts to the behavior of
our make not setting $MAKELEVEL.
