Why are bootstrap compilers installed?

[Florian Weimer]

Is this really necessary?

$ ls -lh /usr/lib/golang/pkg/bootstrap/bin/
total 31M
-rwxr-xr-x. 1 root root 4.4M May  9 09:28 asm
-rwxr-xr-x. 1 root root 4.7M May  9 09:28 cgo
-rwxr-xr-x. 1 root root  16M May  9 09:28 compile
-rwxr-xr-x. 1 root root 5.7M May  9 09:28 link

These compilers shouldn't be needed after the build, right?
So they shouldn't be installed and shipped in the RPM (and neither
the corresponding .a files).

Thanks,
Florian
