OK, we're about talking about Syslinux 5.00x. I looked at the wrong
source file in the first place -- the correct one is actually
core/elflink/load_env32.c.

The only possible paths (hard-coded in search_directories string array)
that ldlinux.c32 could be found are "/boot/isolinux", "/isolinux",
"/boot/syslinux", "/syslinux" and "/".

The ldlinux.c32 could be installed in any path, however Syslinux won't
be able to find it in paths other than those in search_directories
array.

If either Peter or Matt feels that "/boot/extlinux" should be supported,
here goes a patch that adds such support:

Subject: [PATCH] core: Add "/boot/extlinux" path support

Add "/boot/extlinux" path to be looked up when finding ldlinux.c32 and
Syslinux config files.
