configure: Determine system architecture properly on *BSD systems

brad0 · brad0 · commit e3568cedfa56 · 2025-11-17T01:35:02.000-05:00
uname -m on a BSD system will provide the architecture port .e.g.
arm64, macppc, octeon instead of the machine architecture .e.g.
aarch64, powerpc, mips64. uname -p will provide the machine
architecture.
