syslinux: upgrade to versin 3.86

from version 3.36
partly based on the recipe from openembedded project

changes:
  - add cross-build.patch to use poky toolchain
  - mangle LDFLAGS so $LD invocation works
  - use precompiled version of $BTARGET for target (OE)
  - stick on ${sbindir} instead of OE's ${base_sbindir}
