[syslinux] [PATCH] Fix for crash with certain EFIs

Just a reminder:

 _ 6.04-pre1 can be downloaded from kernel.org, and it includes 
pre-built binaries, so no "make" anything is needed (and to some 
degree, not always recommended).

 _ In many cases, testing with pre-built official binaries is desired, 
so others can attempt to reproduce the results, minimizing the impact 
of potential differences in building environments.

 _ All Syslinux-related files should be originated from the same build 
/ version. Mixing, for example, syslinux.efi from one build with 
ldlinux.e64 (or any c32 file) from another build is very much 
discouraged, unless explicitly requested for some very specific test.

 _ It is very easy to mistakenly mix c32 files from one platform (say, 
efi32) with the equivalent c32 from another platform (say, from efi64), 
because they only differ in their respective path directories (they 
have the same name, except for ldlinux.*). Using the "wrong" c32 file 
(e.g. pertaining to a different platform than the one is being 
attempted to boot) will result in unpredictable behavior.

 _ 6.04-pre1 is not "perfect", but it is a relevant test in the current 
context.
