This test had to be changed to deal with systems where the text segment
runs at a different location than the default. The problem is that the
entry address can appear to be outside the text segment, thus causing an
erroneous conclusion that the file isn't executable.
To fix this, we now accept any non-zero entry point as an indication of
executability. This will work most of the time, since only the linker
sets the entry point, and that is likely to be non-zero for most systems. */
