minor bootstrap problem

[Jim Meyering]

I have a directory named `perl' that resides in a `bin'
directory, and that latter happens to be early in my path.
This situation caused automake's bootstrap script to malfunction
because it selected my bin/perl *directory* to use as a perl binary.

Here's a proposed patch to fix that:

2003-11-17  Jim Meyering  <address@hidden>

        * bootstrap: Require not only that `perl' have the executable
        bit set, but also that it is not a directory.
