Well it seems Oscar is building on a 64 bit platform...

And Gene is building inside a 32-bit VM

The text
  GCC supports the x86-64 architecture implemented by the AMD64 processor
  (amd64-*-* is an alias for x86_64-*-*) on GNU/Linux, FreeBSD and
  NetBSD. On GNU/Linux the default is a bi-arch compiler which is able to
  generate both 64-bit x86-64 and 32-bit x86 code (via the -m32 switch).
is from https://gcc.gnu.org/install/specific.html#x86-64-x-x

Would adding '-m32' help against the smell of an optimizer/stripper bug?
;-)

There's already a bunch of '-m32' references around so I'm
guessing
that's already the way it needs to be.

I do not think so.
-m32 parameter is there to compile 32 bits objects on a compiler configured to
compile 64 bits objects by default.
Then the -m32 surelly is already used when compiling the 32 bit version of
Syslinux when using the 64bit GCC
