[kaffe] 'mktemp' check in configure (or kaffe shell script does not work)

[Kiyo Inaba]

Hi,

As the subject line says, configure.in version 1.200 introduced existence check
for 'mktemp' command, but it does not change anything for configure script.
This command is used in 'kaffe' shell script and if we don't have mktemp
(well, this is the case for me on Solaris) the final 'kaffe' script does
not work properly if you set debug flag.
