Subject: [PATCH] Add a LLVM_USE_LINKER that defines the linker to use when
building LLVM
Summary:
This string parameter is passed to -fuse-ld when linking. It can be
an absolute path to your custom linker, otherwise clang will look for
`ld.{name}`.

Before llvm4, both major and minor version updates of llvm were regularly
breaking API. Because of that, the libLLVM library was named in following
format: libLLVM-${major}-${minor}.so
(https://bugs.llvm.org/show_bug.cgi?id=25059)
(https://reviews.llvm.org/D13841)
The package containing this library was called libLLVM${major}_${minor} which
follows our guidelines.
Since llvm4, llvm decided to follow semantic versioning and only break API if
the major version was increased. In addition they do not intend to ever have
minor version other than 0.
(http://blog.llvm.org/2016/12/llvms-new-versioning-scheme.html)
The package was renamed to libLLVM${major}, which no longer follows the naming
guidelines, but since the package contained multiple libraries, it was not
detected.
Since bnc#1049703 the libLLVM${major} package contains only the
libLLVM-${major}-${minor}.so library and no others. This triggers the
shlib-policy-name-error check in our packaging system.
Because the reasons for using the libLLVM-${major}-${minor}.so format are no
longer valid, lets revert back to libLLVM.so.${major}.${minor}.${version}
format. That way the package name matches our guidelines.
