OS X build isn't quite right. darwin hints defines "platform_asm", but this file isn't defined for darwin. This generates a dependency in the build for src/platform_asm.s, which doesn't exist.
Shutting off this config hint allows the build to progress to the link stage, where we get the following error instead.
ld: Undefined symbols: _Parrot_ppc_jit_restore_nonvolatile_registers
