From: Khem Raj <khem.raj@oss.qualcomm.com>

fwupd-efi finds the linker with find_program(cc.get_linker_id()),
which looks for a program named ld.bfd. meson.cross only sets ld, so
meson falls back to PATH and picks up ld.bfd from HOSTTOOLS. That breaks
cross builds on an x86-64 host:

  hosttools/ld.bfd: cannot represent machine `aarch64'

and on x86-64 targets it silently links with the host linker.

Set ld.bfd in an additional cross file
