Platforms not loaded when using self-compiled architecture plugins #2035
Description
Normal Binja:
>>> binaryninja.Platform.list
[<platform: decree-x86>, <platform: freebsd-aarch64>, <platform: freebsd-armv7>, <platform: freebsd-thumb2>, <platform: freebsd-x86>, <platform: freebsd-x86_64>, <platform: linux-aarch64>, <platform: linux-armv7>, <platform: linux-thumb2>, <platform: linux-armv7eb>, <platform: linux-thumb2eb>, <platform: linux-mipsel>, <platform: linux-mips>, <platform: linux-ppc32>, <platform: linux-ppc64>, <platform: linux-ppc32_le>, <platform: linux-ppc64_le>, <platform: linux-x86>, <platform: linux-x86_64>, <platform: mac-aarch64>, <platform: mac-armv7>, <platform: mac-thumb2>, <platform: mac-x86>, <platform: mac-x86_64>, <platform: windows-aarch64>, <platform: windows-armv7>, <platform: windows-thumb2>, <platform: windows-x86>, <platform: windows-x86_64>]
Binja with arch-arm64/master compiled myself and loaded using the instructions:
>>> binaryninja.Platform.list
[<platform: decree-x86>, <platform: freebsd-armv7>, <platform: freebsd-thumb2>, <platform: freebsd-x86>, <platform: freebsd-x86_64>, <platform: linux-armv7>, <platform: linux-thumb2>, <platform: linux-armv7eb>, <platform: linux-thumb2eb>, <platform: linux-mipsel>, <platform: linux-mips>, <platform: linux-ppc32>, <platform: linux-ppc64>, <platform: linux-ppc32_le>, <platform: linux-ppc64_le>, <platform: linux-x86>, <platform: linux-x86_64>, <platform: mac-armv7>, <platform: mac-thumb2>, <platform: mac-x86>, <platform: mac-x86_64>, <platform: windows-armv7>, <platform: windows-thumb2>, <platform: windows-x86>, <platform: windows-x86_64>]
Notably all the aarch64 platforms are missing. This is a problem as I'd like to be able to test my arm64 lifter changes, but they require a platform to run.
