[PATCH] uClinux support for AC_FUNC_FORK

[Bernardo Innocenti]

This is required when cross-compiling for uClinux targets
because the kernel lacks a working fork() implementation
even though uClibc might have a fake version of it.

I have FSF copyright assignment papers on file, covering
also the autoconf project.

        * lib/autconf/functions.m4 (AC_FUNC_FORK): Don't assume working fork()
        when cross-compiling for *-*-uclinux*.
