maximum command line length check takes more than an hour on AmigaOS with pdksh

[Dalibor Topic]

Hi all,

the libtool m4 macros check among other things for maximum command line length.
As Tony Wyatt found out [1] the test takes more than an hour to complete on
m68k-amigaos using pdksh. 

I've attached a patch that sets maximum command line length on the amiga to 8K.
Tony tested it, and it worked for him. So it would be nice if it could find
it's way into the next libtool release.

cheers,

p.s. We have more patches for libtool pending in kaffe 1.1.0 [2]. I'll send you
small patches over the next week on this forum, if that's o.k.
