boost and cray : `./build.sh: line 15: 42650 Illegal instruction $@`

I tried to build boost 1.68 using the cray compiler on a cray machine. Command: `boost_1_68_0/tools/build> ./bootstrap.sh --with-toolset=cc` and `boost_1_68_0> ./bootstrap.sh --with-toolset=cc`

but the bootstrap.log shows me an error in both cases:
```
./bootstrap/jam0 -f build.jam --toolset=cc --toolset-root= clean

It does work with the intel-linux compiler though.

It seems from the documentation that the support for the Cray compiler has been discontinued?
