- Rather than adjusting TARGET_VENDOR, which results in our TARGET_SYS
matching the external toolchain, override TARGET_PREFIX to match external,
and leave TARGET_SYS alone
- Grab the optimized files out of the toolchain if available
- Create a symlink in sysroot to ensure the sysroot layout matches toolchain
expectations (optimized files in a subdir)
