commit e59ced49f3d19a6aa7a0d4c2c156571e56d3eef3 Author: Patrick Georgi patrick@georgi-clan.de Date: Thu Aug 20 17:53:52 2015 +0200
crossgcc: Fix x86_64-elf target's -m16 support
It still needs to pass --32 (yes, 32) to the assembler. x86_64-linux does this (through some other config file), x86_64-elf did not.
This fixes building SeaBIOS with our x86_64-elf multilib compiler.
