I don't think you need to change anything about Built-Using. That seems
like exactly the sort of reason anticipated by DFSG compliance. The
clarification in Policy is because the previous wording would have
required literally every program in the archive written in C to declare
Built-Using against the version of GCC used to build them because of the
nature of libgcc, and at the request of the release team to not use
Built-Using for library update purposes.

Yes, or at least the portions relevant to the code that's being statically
linked. The resulting binary is a derivative work of the syslinux-efi
package, so you need to follow its license.
