ci/build-freebsd: use march=native for QEMU hosted build

This is workaround to not emit instructions that are broken with current
version of QEMU used in CI job.

Fixes SIGBUS on valid code when executed in QEMU caused by issue with
CVTPS2PD instruction.

QEMU issue:
https://gitlab.com/qemu-project/qemu/-/issues/1377

QEMU fix:
abd41884c5

Should be resolved after QEMU update to 8.2.0:
