libtool 1.5.10: AC_LIBTOOL_SYS_MAX_CMD_LEN causes system crash

Hi!

AC_LIBTOOL_SYS_MAX_CMD_LEN reliably causes a system crash under Tru64 Unix, 
V5.1B-PK4 if the number of length of command line arguments is not limited 
(one can disable length checking with the proc:exec_disable_arg_limit kernel 
option).

I do not know if there is any explicit command in Tru64 to query the maximum 
length of the command line.  But if

/sbin/sysconfig -q proc exec_disable_arg_limit

returns

proc:
exec_disable_arg_limit = 1

then the iterative test for the maximum length MUST NOT be run.  Otherwise, 
the system will crash.  I hope that a corresponding check will be integrated 
into future versions of libtool.

My config: libtool 1.5.10, automake 1.9.4, autoconf 2.59.

Regards,
Hans
