Mister Anvin,
care to share what's the status of the "ld?" problemo,
is anyone working on it?

It would be maravilloso if syslinux can continue to build and test with latest
and greatest.

There have been a discussion about the -fPIC option a few month ago
(november or december 2015). I don't remember what exactly it was
about. I think I said I would submit a patch that add -fPIC for 32
bits even thought it wouldn't have an actual effect regarding current
compilers.

This option is definitely required for 64 bits, and it is
theoretically required for 32 bits. But I haven't investigated the
current issue.

Is there any chance that this issue might be somehow related to some 
'make' parameter such as "make EFI_BUILD=1 ARCH=i386" (either,
or both
of them, or similars, or any other one), which we mildly discussed 
during 2015Nov?

I cannot help but wonder whether executing a 'make spotless' before 
executing the final 'make' could generate a different result / 
message(s) (considering that the Syslinux binaries were built more than 
once while testing).

Completely unrelated to my comments above... Some patches that "might"
give some clue to some knowledgeable developer (let's hope):

gnu-efi, syslinux: Support gcc < 4.7
cgit.openembedded.org/openembedded-core/commit/meta/recipes-devtools/sys
linux/syslinux?id=90e7cfebc6a9ac4b229b45c6a7dc95218efe55c5

syslinux: Dont bypass gcc driver for dependency generation options
cgit.openembedded.org/openembedded-core/commit/meta/recipes-devtools/sys
linux/syslinux?id=f3ac32e0bc83d7aeea3e84258c258c2bb6dab44e

syslinux: Set LD to avoid using build host ld
cgit.openembedded.org/openembedded-core/commit/meta/recipes-devtools/sys
linux/syslinux_6.03.bb?id=c4897af85eace49e3c27aebc1448227105286e30


Regarding "latest and greatest", there are several sections of (GPL) 
code being used in Syslinux that might benefit from some updated 
versions (some of them have not received updates in Syslinux's code 
since 2010).

It isn't just 32 vs 64 bits, it is also 32 bit BIOS vs 32 bit EFI, and their
requirements differ.
