sys-devel/clang-common: install config files for llvm internal triples
* Also drop a redundant doclang_cfg invocation.
* This change is to ensure that invoking clang instead of ${TARGET}-clang
also uses the installed config files. Problem being that llvm sees its
target triple differently from what Gentoo uses and therefore may lead
to it ignoring the installed config files. For example x86 Gentoo uses
i686-pc-linux-gnu as its CHOST and this leads to
i686-{pc,unknown,gentoo}-linux-gnu config files to be installed, this is
while llvm internally prefers to use i386-pc-linux-gnu as its target when
not invoked explicitly with a target in the executable name or with --target=
leading it to ingore them when invoked with just "clang". This also affects
multilib so on amd64 clang -m32 exhibits the same issue.
* This doesn't address irregularities with prefix installs where the os version
and the lack of vendor field may lead to this same issue.
