Prefer full LTO (-flto) over ThinLTO for QEMU (-flto=thin)
1024f66 
This seems to be measurably faster and does not appear to impact compile
time too much.

hyperfine '~/cheribsd-boot-benchmark.sh /local/scratch/alr48/cheri/output/sdk/bin/qemu-system-cheri128.fulllto.8f17bc88e6b' '~/cheribsd-boot-benchmark.sh /local/scratch/alr48/cheri/output/sdk/bin/qemu-system-cheri128.thinlto.8f17bc88e6b' '~/cheribsd-boot-benchmark.sh /local/scratch/alr48/cheri/output/sdk/bin/qemu-system-cheri128.without-lto.8f17bc88e6b'
Benchmark #1: ~/cheribsd-boot-benchmark.sh /local/scratch/alr48/cheri/output/sdk/bin/qemu-system-cheri128.fulllto.8f17bc88e6b
  Time (mean ± σ):      2.395 s ±  0.062 s    [User: 2.233 s, System: 0.159 s]
  Range (min … max):    2.341 s …  2.545 s    10 runs

Benchmark #2: ~/cheribsd-boot-benchmark.sh /local/scratch/alr48/cheri/output/sdk/bin/qemu-system-cheri128.thinlto.8f17bc88e6b
  Time (mean ± σ):      2.470 s ±  0.015 s    [User: 2.311 s, System: 0.167 s]
  Range (min … max):    2.453 s …  2.502 s    10 runs
