host package uses the wrong clang compiler

Project Member Reported by yunlian@chromium.org, Jun 22 2016 
USE="clang" sudo emerge btsocket


 creating build/temp.linux-x86_64-2.7/src
btsocket-0.0.1-r11: x86_64-pc-linux-gnu-clang -O2 -pipe -fPIC -I/usr/include/python2.7 -c src/btsocket.c -o build/temp.linux-x86_64-2.7/src/btsocket.o
btsocket-0.0.1-r11: unable to execute 'x86_64-pc-linux-gnu-clang': No such file or directory
btsocket-0.0.1-r11: error: command 'x86_64-pc-linux-gnu-clang' failed with exit status 1

This is because the function clang-setup-env will set the CC to
"${CHOST}-clang". For host, there is no such wrapper, so the error happens.

commit b96171736c728a8fedee249523c9b6a99ba5c488

toolchain-funcs.eclass: do not accept "USE=clang" for host package.

When building host package with USE=clang, it will set the compiler
to x86_64-pc-linux-gnu-clang. There is no such wrapper and the build
fails. This CL stops to set CC for host package even USE=clang is set.

BUG= chromium:622477 
TEST=sudo USE="clang" emerge btsocket passes.
