SUCCESS
the cosmo mono repo will now build using cosmocc
WARNING
if you run `make clean` then you'll have to download it again
CONSIDER
you can install the cosmocc toolchain you just downloaded as follows
sudo chmod 01777 /opt
rm -rf /opt/cosmocc
mv o/third_party/gcc /opt/cosmocc
ln -sf /opt/cosmocc o/third_party/gcc
echo 'export PATH="/opt/cosmocc/bin:$PATH"' >>~/.profile
then just recreate the symlink after cleaning. please note that you
should NEVER need to use make clean with the cosmo mono repo, since
our Makefile is flawless. if make clean actually helps, file a bug.

PROTIP
running these commands
rm -rf o
sudo mount -t tmpfs -o size=10G,noatime,nodiratime /dev/shm o
ln -sf /opt/cosmocc o/third_party/gcc
makes the mono repo build faster
