>Description:
Trying to build devel/idutils is stuck in an endless loop in configure
that keeps re-executing itself.

As far as I can tell when configure is started the sequence of events
is as follows:

. CONFIG_SHELL is set in the environment
. _as_can_reexec is not set
. _as_can_reexec is set to "no" in the environment
. configure re-execs itself
. this time the re-exec check is passed
. _as_can_reexec is unset
. LINENO support is tested and /bin/sh doesn't support it
. configure.lineno is generated with $LINENO substituted with sed
. configure.lineno is sourced with "."
. goto beginning

>How-To-Repeat:

>Fix:
As a workaround

  CONFIG_SHELL=/usr/pkg/bin/bash make

helps to break the endless loop since bash provides LINENO.
